Question

The quadratic polynomial whose zeroes are 5 and -5 is: (A) x^2 - 36 (B) x^2 - 25c (C) x^2 + 12x + 36 (D) x^2 - 10x + 25

Answer 1

Answer:

Option (B) : x² - 25

Step-by-step explanation:

Given,

Sum of the zeroes, S = 5 + (-5) = 0

Product of the zeroes, P = 5 × ( -5) = -25

Required polynomial

= k { x² - S x + P }

= x² - 0 x + (-25)

= x² -25
