Question

The number of polynomials having zeros as -2 and 5 is a)1 b)2 c)3 d)more than 3

Answer 1

d) More than 3.

Explanation:

The polynomial (x - 5)(x + 2) ( = x^2 - 3x + 10) has zeros of -2 and 5 but so have the polynomials formed by multiplying this by any integer:

- for example 2(x - 5)(x + 2) , 4(x - 5)(x + 2) and so on.
