• (x - 8)(x + 3)
• (x + 8)(x - 3)
• (x + 6)(x - 4)
• (x + 12)(x - 2)

Factor:

x² + 11x + 24

• (x + 6)(x + 4)

• (x + 12)(x + 2)

• (x - 8)(x - 3)

• (x + 8)(x + 3)

Factor:
x² - 25

• ( x + 5 ) ( x - 5 ) 
• ( x - 5 ) ( x - 5 )

• Prime

Which of the following trinomials is a perfect square trinomial?

• r² - 6r + 36
• 4y² + 10y + 25

What do the "Zeros" represent on a quadratic equation graph?

• x-intercepts

• y-intercepts

• vertex

• focus

What are the x- intercepts?

• x= 0 and x= -4
• x= 0 and x= 4

• Difference of squares

• Group

Factor:

8x² + 10x + 16xy

• 18x² +16xy

• 2 (4x² + 5 + 8y)

• 2x (4x + 5 + 8y)

• 8x² + 10x + 16xy

Solve by factoring: x² +14x +48 = 0

• x = -8 and x = 6

• x = -4 and x = 6

• x = 8 and x = 6

• x = -8 and x = -6

Solve for the values of x:
(x - 3)(x + 6) = 0

• { -3, -6 }
• { 3, -6 }
• { -3, -6 }
• { 3, 6 }
