Question. Find the zeroes of the following quadratic polynomials and verify the relationship between the zeroes and the coefficients.
(i) 6x2 – 3 – 7x                            (ii) 4u2 + 8u                              (iii) 4s2 – 4s +1 
Sol. (i) We have,
   p (x) = 6x2 – 3 – 7x
⇒ p (x) = 6x2 – 7x – 3 (In general form)
           = 6x2 – 9x + 2x – 3
           = 3x (2x – 3) +1 (2x – 3) = (2x – 3) (3x +1)
The zeroes of polynomial p (x) is given by
   p (x) = 0
⇒ (2x – 3) (3x +1) = 0 ⇒ x = 3/2 -1/3,
Thus, the zeroes of 6x2 – 7x – 3 are α = 3/2 and β = – 1/3

Assignments For Class 10 Mathematics Polynomials

Therefore, product of zeroes = Constant term/Coefficient of x2
(ii) We have,
p (u) = 4u2 + 8u  ⇒    p(u) = 4u (u + 2)
The zeroes of polynomial p (u) is given by
p (u) = 0  ⇒  4u (u + 2) = 0
∴   u = 0, – 2
Thus, the zeroes of 4u2 + 8u are a = 0 and b = – 2
Now, sum of the zeroes = a + b = 0 – 2 = – 2
and (Coefficient of u )/ Coefficient of u 2=-8/4= -2
Therefore, sum of the zeroes = -(Coefficient of u) /(Coefficient of u2)
Again, product of the zeroes = αβ = 0 x (- 2) = 0 and Constant term/Coefficient of u2 =0/4=0
Therefore, product of zeroes = Constant term/Coefficient of u2
(iii) We have,
    p (s) = 4s2 – 4s +1
⇒ p (s) = 4s2 – 2s – 2s +1 = 2s (2s -1) -1 (2s -1) = (2s -1) (2s -1)
The zeroes of polynomial p (s) is given by
    p (s) = 0
⇒ (2s -1) (2s -1) = 0
⇒ s = 1/2-1/2,
Thus, the zeroes of 4s2 – 4s +1 are

and Constant term/Coefficient of s 2 = 1/4
∴  Product of zeroes = Constant term/Coefficient of s 2

Question. Verify that the numbers given alongside the cubic polynomial below are their zeroes. Also verify the relationship between the zeroes and the coefficients.
              x3 – 4x 2 + 5x – 2; 2,1,1
Sol. Let p(x) = x3 – 4x2 + 5x – 2
On comparing with general polynomial p(x) = ax3 + bx2 + cx + d, we get a =1, b = – 4 , c = 5 and d = – 2.
Given zeroes 2, 1, 1.
∴ p(2) = (2)3 – 4(2)2 + 5(2) – 2 = 8 -16 +10 – 2 = 0
and p (1) = (1)3 – 4 (1)2 + 5(1) – 2 =1 – 4 + 5 – 2 = 0.
Hence, 2,1 and 1 are the zeroes of the given cubic polynomial.
Again, consider a = 2, b =1, g =1
∴ α + β + γ = 2 +1 +1 = 4

Question. If the product of two zeros of the polynomial
p(x) = 2x3 + 6x2 – 4x + 9 is 3, find the third zero of the polynomial.
Solution. If α, β, and γ be the three zeros of p(x). Then,
αβγ = – 9/ 2
Since, αβ = 3,
we get γ = − × = − 9/ 2 × 1/3 = -3/2
Thus, the third zero of p(x) is − 3/ 2

Question. Find the zeroes of following polynomials by factorisation method and verify relation between the zeroes and coeffcients of polynomials.
(A) 2x2 + 2/ 7 x + 4 3 
(B) 2s2 − (1 + 2 √2)s + √2 
(C) 7y2 – 11/3  y – 3/ 2 
Solution. (A) Let f(x) = 2x2 + 7/2 x + 3/4 = 8x2 + 14x + 3
(Multiplying the given equation by 4)
= 8x2 + (12x + 2x) + 3
= 8x2 + 12x + 2x + 3
= 4x(2x + 3) + 1(2x + 3)
= (2x + 3)(4x + 1)
The zeroes of f(x) are given by f(x) = 0.
So, the value of 2x2 + 7/2 x + 3/4 is zero when
x = – 3/2 or x = –1/ 4
⇒ x = – 3/2 , – 1/4

Question. If a and b are the zeros of the polynomial p(x) = 4x2 – 2x – 3, find the value of 1/α + 1/β . 
Solution. Here, α+ β = 2/ 4 or 1/ 2 and α.β = −3/ 4 .
So, 1/α + 1/β = α + β /αβ = 1/2/-3/4 =-2/3

Question. If one of the zeros of polynomial p(x) =
(k − 1)x2 – kx + 1 is −3, find the value of k.
Solution. Since, (–3) is a zero of p(x), we have,
(k – 1)(–3)2–k(–3) + 1 = 0
⇒ 9k–9 + 3k + 1 = 0,
⇒ 12k = 8 ⇒ k = 2/ 3

Question. If α and β be the roots of the equation x2 − 1 = 0 , then show that: α + β = 1/α + 1/β
Solution. Here, α + β = 0/ 1 = 0
[∵ Sum of roots = Coefficient of x / Coefficient of x2 ]    
Also, 1/α + 1/β = α + β /αβ = 0/1 = 0
Thus, α + β = 1/α + 1/β

Question. A teacher asked 10 of his students to write a polynomial in one variable on a paper and then to handover the paper. The following were the answer given by the students:
2x + 3, 3x2 + 7x + 2, 4x3 + 3x2 + 2, x3 + √3x + 7, 7x + √7 , 5x3 – 7x + 2, 2x3 + 3 – 5 x , 5x – 1/2 , ax3 + bx2 + cx + d, x + 1 x .
Answer the following Questions:
(A) How many of the above ten are not polynomials?
(B) How many of the above ten are quadratic polynomials?
Solution. (A) Three, namely: x3 + √3x + 7 , 2×2 + 3 − 5/x , x+1/x
(As they contain square roots of the variable and negative power of x)
(B) One, namely 3×2 + 7x + 2

Question. If one of the zeroes of the quadratic polynomial f(x) = 4x2 – 8kx – 9 is equal in magnitude but opposite in sign of the other, then find the value of k.
Solution. f(x) = 4x2 – 8kx – 9
Let one of the zeroes of the polynomial be 􀁄
and the other zeroes be – α
Sum of zeroes = (− b /a) = 8k/4
α + (- α) = 0
So, 8k/ 4 = 0 ⇒ k = 0

Question. Can (x – 5) be the remainder on division of a polynomial p(x) by (x + 8)? 
Solution. No. We know that we cannot divide the polynomials which have same degree.
As we can see that degree of (x – 5) = degree of (x + 8)
So, they are not divisible.

Question. If the zeros of the polynomial x3 – 2x2 + x + 1 are a – b, a and a + b, then find the values of a and b.
Solution. As (a – b), a and (a + b) are zeros of x3 – 3x2 + x + 1, we have:
a – b + a + a + b = 3
⇒ 3a = 3, or a = 1 …(i)
a (a – b) + a (a + b) + (a – b) (a + b) = 1
⇒ 3a2 – b2 = 1 …(ii)
and (a – b) a (a + b) = –1
⇒ a(a2 – b2) = –1 …(iii)
From (i) and (ii), we have b = ± √2
Thus, a = 1, b = ± √2

Question. Form a quadratic polynomial, the sum and product of whose zeroes are (–3) and 2 respectively. 
Solution. A general form of a quadratic polynomial is
ax2 + bx + c
Here, α + β = − b/ a = – 3 and a.b = − b/ a = 2
where, a and b are the roots of given polynomial.
So, the required polynomial is x2 + 3x + 2.

Question. Find the value of k for which the roots of the equation 3x2 − 10x + k = 0 are reciprocal of each other. 
Solution. Given, equation is 3×2 – 10x + k = 0, where roots are reciprocals of each other.
Let the roots be α and 1/ α 
∴ Product of roots = c/ a
⇒ α . 1/α = k /3 [∵ a = 3, b = – 10, c = k]
⇒ 1 = k /3
⇒ k = 3

Question. What number should be added to the polynomial x2 – 5x + 4 so that 3 is the zero of the polynomial?
Solution. Let k be the number to be added to the given polynomial.. Then the polynomial becomes x2 – 5x + (4 + k)
As 3 is the zero of the polynomial, we get:
(3)2 – 5(3) + (4 + k) = 0
⇒ (4 + k) = 15 – 9
⇒ 4 + k = 6
⇒ k = 2
Thus, 2 is to be added to the polynomial

Question. If the zeroes of a polynomial x2 – 8x + k = 0, is the HCF of (6, 12), then find the value of k. 
Solution. HCF of (6, 12) = 6
So, 6 is one of the roots of the polynomial.
f(x) = x2 – 8x + k = 0
f(6) = (6)2 – 8(6) + k = 0
36 – 48 + k = 0
–12 + k = 0 ⇒ k = 12.

Question. Find a quadratic polynomial whose zeroes are reciprocals of the zeroes of the polynomial f(x) = ax2+ bx + c, a ≠0 , c ≠ 0. 
Solution. Let α, β be the zeroes of f(x) = ax2 + bx + c. Thus
α + β = – b/ a and αβ = c/a
Now, 1/α + 1/β = α + β / αβ = -b/a/c/a = – b/c
1/α . 1/β = 1/αβ = 1/c/a = a/c
∴ Polynomial is: x2 – (sum of roots) x
– product roots
x2 – (-b/c)x + a/c = 0
⇒ cx2 + bx + a = 0
So, the required polynomial is cx2 + bx + a.

Question. If the zeroes of the polynomial x2 + px + q are double the value to the zeroes of 2x2 – 5x − 3, find the value of p and q. 
Solution. Let α and β are zeroes of the 2x2 – 5x – 3
α + β = – b/a = 5/2
αβ = c/a =− 3/2
According to the question,
2α and 2β are zeroes of x2 + px + q
2α + 2β = –p ⇒ 2(α + β) = –p
2 x (5/2) = -p
= –p [from eqn. (i)]
p = –5
2α × 2β = q ⇒ 4αβ = q
4 x(- 3/2) q = –6
Hence, p = –5 and q = –6.

Question. Find the value of k such that the polynomial x2 – (k + 6)x + 2(2k 􀈻 1) has the sum of its zeros equal to half of their product. 
Solution. Given polynomial is :
p(x) = x2 – (k + 6) x + 2(2k – 1)
In the given quadratic equation:
a = 1
b = – (k + 6)
c = 2(2k – 1)
Sum of zeroes = – b/ a
= k + 6 …(i)
Product of zeroes = c/a
= 2(2k – 1) …(ii)
According to the given condition:
Sum of the zeroes = 1 /2 × Product of zeroes
⇒ k + 6 = 1/ 2
× 2 (2k – 1)
⇒ k + 6 = 2k – 1
⇒ 2k – k = 6 + 1
⇒ k = 7
Hence, the value of k is 7.

Question. Find the quadratic polynomial sum and product of whose Zeroes are – 1 and – 20 espectively. also, find the zeroes of the polynomial so obtained.
Solution. Let α and β the zeroes of the polynomial.
Given : sum of zeroes, α + β = – 1
product of zeroes, αβ = – 20
Equation of polynomial :
x2 – (sum of zeroes) x + product of zeroes = 0
∴ x2 – (– 1)x + (– 20) = 0
⇒ x2 + x – 20 = 0
On spliting the middle term,
x2 + 5x – 4x – 20 = 0
⇒ x(x + 5) – 4(x + 5) = 0
⇒ (x – 4) (x + 5) = 0
⇒ x = 4, – 5
Hence, the zeroes of the polynomial are 4 and –5.

Then, α + 7α = 8α = 8 /3 …..(i)
and α.(7α) = 7α2 = 2k + 1/3 …..(ii)
From (i) α = 1/ 3 . So, the two roots are 1/ 3 and 7/ 3

= x2 – (–2)x – 3 = x2 + 2x – 3
Here, a = 1, b = 2, c = –3
− b/ a = −2 /1 =- 2
Sum of zeroes = − b/ a = 2 [using eqn. (i)]
Also, c/a = -3/1 = -3
