Q. 26

# A quadratic polynomial, the sum of whose zeroes is 0 and one zero is 3, isA. x2 – 9B. x2 + 9C. x2 + 3D. x2 – 3

Given,

One of the polynomial is 3,

Sum of the zeros = 0

Now

Let the other zero be x,

x + 3 = 0

x = – 3

So,

Zeros of the polynomial are 3 and – 3

Product of the zeros = 3 × – 3 = – 9

Polynomial with zeros 3 and – 3 = x2 – (0)x + ( – 9) = x2 – 9
