Factoring Quadratics When A Is Not 0

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

Factor and solve:

z² − 14z + 45 = 0

• z = 1, 45

• z = −1, 45

• z = −5, 9

• z = 5, 9

Solve using the Zero-Product Property

(x −11)(5x + 1) = 0

Factor and Solve:

m² − 100 = 0

• m = 50 , −50

• m = 10

• m = 10, −10

• m = −10
