Factoring Using Quadratic Equation

Convert x² - 9x + 20 to factored form and solve.

• (x-10)(x+2); x = -2, 10

• (x+4)(x+5); x = -5, -4

• (x-4)(x-5); x = 4, 5

• Not factorable

What are the solutions to this equation? (x-3)(x+2)=0

• x=3,-2

• x=-3,2

• x=2,3

• x=3,2

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

What property would you use to solve the following?
(x-3)(x+2)=0

• Commutative Property

• Associative Property

• Zero Product Property

• Inverse Property

Which answer choice correctly shows the quadratic equation above in factored form?

• (x + 7)(x - 2) = 0

• (x - 7)(x + 2) = 0

• (x - 7)(x - 2) = 0

• (x + 7)(x + 2) = 0

Solve by factoring: x² + 3x - 18 = 0
