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

Hi there! The answer is A) x = 3 or x = 6

$2 {x}^{2} - 18x + 36 = 0$
Divide by 2.

${x}^{2} - 9x + 18 = 0$
Factor.

$(x - 3)(x - 6) = 0$
Use the rule AB = 0 gives A = 0 or B = 0

$x - 3 = 0 \: \: or \: \: x - 6 = 0 \\ x = 3 \: \: \: \: \: \: \: \: \: or \: \: x = 6$

The answer is A) x = 3 or x = 6
