Solving Quadratic Equations by Factoring GCF

Solve by factoring. (HINT: Factor GCF 1st)

• x = 3, x = -6

• x = 0, x = 2

• x = 2, x = 3

• x = -2, x = 1

Factor the following quadratic. Don't forget to look for a GCF:

2x² - 2x - 180

• 2(x+9)(x-10)

• 2(x-9)(x+10)

• (2x+1)(x-1)

• (2x-45)(x+2)

Factor and Solve: Remember the two numbers you choose when factoring, are not your solutions to the equation!

a² + 2a − 24 = 0

• a = −6, 4

• a = 6, −4

• a = 12, −2

• a = 8, −3
