Solving Quadratics

Solve using the Zero-Product Property.

7x(x − 6) = 0

• x =7 and x = −6

• x = 0 and x = 6

• x = 0 and x = −6

• x = 7 and x = 6

Solve using the Zero-Product Property

(x −11)(5x + 1) = 0

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

x² + 13x + 12 = 0

• x = −12, −1

• x = 12, 1

• x = 13, 1

• x = −13, −1

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

• a = −6, 4

• a = 6, −4

• a = 12, −2

• a = 8, −3
