What property states that if the product of two real numbers is zero, then either of the two is equal to zero or both numbers are equal to zero.

• Zero Product Property

• Square Root Property

• Distributive Property

Using common monomial factoring, the GCF of the expression 3x² + 12x is ____________.

• 3x

• 3

• x

Factor x² - 25 = 0.

• (x + 5) (x + 5)

• (x - 25) (x + 1)

• (x - 5) (x + 5)

What is the standard form of the quadratic equation x² - 2x = 1?

• x² - 2x - 1 = 0

• x² - 2x + 1 = 0

• x² - 2x - 1

• (x+3)

• (x-9)

• (x+9)

• (x-21)

• x=7; x=5

• x=-7; x=-5

• x=7; x=-5

• x=-7; x=5

• x=5

• x=-5

• x=2

• x=-2

Factor 6x²-27x

• (6x+1)(x+3)
• 3x(2x-9)
• 6x(x-9)
• (3x-9)(2x+3)

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
