Factoring and Solving GCF

Solve by factoring:
 x² - 9x + 20 = 0

• x = -4 and x = -5

• x = 20 and x = -9

• x = 4 and x = 5

• x = -4 and x = 5

Solve the equation by factoring:

x² - 6x = -8

• x=2 and x=4

• x= -2 and x= -4

• x= -2 and x=4

• x=2 and x= -4

Factor:
 2m² + 3m - 9

• 2(m + 3)(m - 3)

• (2m - 3)²

• (m + 3)(2m - 3)

• (2m + 3)(m - 3)

Factor:  
x² -17x - 60

• (x - 20)(x + 3)

• (x - 3)(x + 20)

• (x - 3)(x - 20)

• (x + 3)(x + 20)
