RS Aggarwal Class 10 Solutions Chapter 2 Polynomials MCQS

Question 1.
Solution:
(d) √2 x2 – 3√3 x + √6 is polynomial, others are not polynomial.

Question 2.
Solution:
(d) x + 3x is not a polynomial, other are polynomial.

Question 3.
Solution:
(c) Let f(x) = x2 – 2x – 3
= x2 – 3x + x – 3
= x(x – 3) + 1(x – 3)
= (x – 3)(x + 1)
If x – 3 = 0, then x – 3
and if x + 1 = 0, then x = -1
Zeros are 3, -1

RS Aggarwal Class 10 Solutions Chapter 2 Polynomials MCQS 5

Question 8.
Solution:
(c) Sum of zeros = 3
Product of zeros = -10
Polynomial : x2 – (Sum of zeros) x + Product of zeros
= x2 – 3x – 10

Question 9.
Solution:
(c) Zeros are 5 and -3
Sum of zeros = 5 – 3 = 2
Product of zeros = 5 x (-3) = -15
Polynomial: x2 – (Sum of zeros) x + Product of zeros
= x2 – 2x – 15

Question 10.
Solution:
(d)

Question 11.
Solution:
(b) Let f(x) = x2 + 88x +125
Here, sum of roots = −ba = -88
and product = ca = 125
Product is positive,
Both zeros can be both positive or both negative.
Sum is negative.
Both zeros are negative.

Question 12.
Solution:
(b) α and β are the zeros of x2 + 5x + 8
Then sum of zeros (α + β) = −ba = −51 = -5

Question 13.
Solution:
(c) α and β are the zeros of 2x2 + 5x – 9
Product of zeros (αβ) = ca = −92

Question 14.
Solution:
(d) 2 is a zero of kx2 + 3x + k
It will satisfy the quadratic equation kx2 + 3x + k = 0
k(2)2 + 3x2 + 1 = 0
4k + 6 + k = 0
=> 5k = -6
k = −65

Question 15.
Solution:
(b) -4 is a zero of (k – 1) x2 + 4x + 1
-4 will satisfy the equation (k – 1) x2 + kx + 1 = 0
=> (k – 1)(-4)2 + k(-4) + 1 =0
=> 16k – 16 – 4k + 1 = 0
=> 12k – 15 = 0
=> 12k = 15
=> k = 1512 = 54

Question 16.
Solution:
(c)

Question 20.
Solution:
(a) α, β, γ are the zeros of x3 – 6x2 – x + 30
Then αβ + βγ + γα = ca = −11 = -1

Question 21.
Solution:
(a) α, β, γ are the zeros of 2x3 + x2 – 13x + 6, then
αβγ = −da = −62 = -3

Question 22.
Solution:
(c) α, β, γ are the zeros of p(x) such that
