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

What are the roots?
(x + 5)(2x - 3) = 0

• x = 5 ; x =  -³/₂
• x = -5 ; x = ³/₂
• x = -5 ; x = 3
• 2x² + 7x - 15

What are the roots?
2x² + 2x - 12 = 0

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

What is the standard form for a Quadratic?

• ax²+ bx = - c
• x = -b ± √(b²-4ac) / 2a
• ax² + bx + c
• y = mx + b

Solve the equation using square roots.
x² = 121

• 60.5
• ± 11
• ± 12
• 11

Use the square root property to solve the Quadratic Equation.
2(x - 4)² = 200

• ±10
• -14, 6
• -6, 14
• 100

Solve the equation using the zero product property.
3x ( 2x - 4) = 0

• x = -1/3 or x = -2
• x = 0 or x = 2
• x = 0 or x = -2
• x = -1/3 or x = 2
