Question

Factor to find the zeros of the function defined by the quadratic expression. 2x2 − 18x + 36 A) x = 3 or x = 6 B) x = 3 or x = −6 C) x = −3 or x = 6 D) x = −3 or x = −6

Answer 1

A) x=3 or x=6

Explanation:

Factor out the GCF : 2(x^2-9x+18)

Then, set to zero.

2(x^2-9x+18)=0

2(x-3)(x-6)=0

x=3 or x=6
