AKS 1/22/58 Final Review

Solve by Factoring: (a = 1)

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 by Factoring: (a is not 1)

2x² - 5x - 12 = 0

• x = -4 and x = -6

• x = 4 and x = -3/2

• x = 4 and x = 6

• x = -4 and x = 3/2

Solve using the quadratic formula.

2x² - 9x - 35 = 0

a = ______ b = ______ c = ______

• x = 7/2, x = -6

• x = -2.5, x =5

• x = -3/7, x =6

• x = -2.5, x = 7

Solve Using the Quadratic Formula

x² + 4x = 32

1.) Do the inverse operation to make one side = 0

2.) a = _____ b = ______ c = _____

• -10 & -4

• -4 & 10

• -8 & 4

• 8 & -4
