Solve quadratic equations by factoring and using the zero product property

Solve quadratic equations having real solutions by factoring. Based on high school Common Core standard A-REI.B.4b and TEKS Algebra I standard 8A, grade9

Which equation is x^2 + 2x = 0 written in factored form?

x ⋅x + 2⋅x = 0 x(x + 2) = 0 x^2 = −2x
What is the solution set for x(x + 2) = 0?

x = 0 x = 2 x = 0 or x = −2 x = 0 or x = 2
Solve: (x − 2)(x + 1) = 0

x = −1 or x = 2 x = −1 or x = −2 x = 1 or x = 2 x = 1 or x = −2
