## MCQ Questions for Class 10 Maths Polynomials with Answers

Q.1. If one zero of the quadratic polynomial x² + 3x + k is 2, then the value of k is
(a) 10
(b) -10
(c) 5
(d) -5

Q.2. If the zeroes of the quadratic polynomial x2 + (a + 1) x + b are 2 and -3, then
(a) a = -7, b = -1
(b) a = 5, b = -1
(c) a = 2, b = -6
(d) a – 0, b = -6

Q.3. The zeroes of x2–2x –8 are:
(a) (2,-4)
(b) (4,-2)
(c) (-2,-2)
(d) (-4,-4)

Answers(b) x2–2x –8 = x2–4x + 2x –8
= x(x–4)+2(x–4)
= (x-4)(x+2)
Therefore, x = 4, -2.
