solving quadratics practice

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

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

Solve:   $5x^2-45=0$  

•  $x=3$  

•  $x=-3$  

•  $x=3$  and  $x=-3$  

•  $x=0$  ,  $x=3$  , and  $x=-3$  

Solve by factoring.

• -4, 2

• -2, 4

• -16

• -4

Factor:  x² + 9x + 18

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

Solve the equation by factoring:

x² - 6x = -8

• x=2 and x=4

• x= -2 and x= -4

• x= -2 and x=4

• x=2 and x= -4

Which method is most efficient to solve:
x²  -  11x + 10 = 0

• Square Roots
• Factoring
• Completing the Square
• Quadratic Formula

What are the roots?
2x² + 2x - 12 = 0

• x = 3 ; x = -3
• x = 12 ; x =  -12
• x = -3 ; x = 2
• x = -2 ; x = 2
