Question

Factor to find the zeros of the function defined by the quadratic expression. 2x2 − 18x + 36

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

Answer 2

2 x square - 18 x + 36

2 x square - 6 x -12 x + 36

2 x (x - 3 )- 12 (x - 3 )

x - 3 2 x =12

x = 3 x =6
