Solving Quadratics

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

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

What are the x- intercepts?

• x= 0 and x= -4
• x= 0 and x= 4
• y= 0
• x= 2

Solve
x² + 2x - 24 = 0

• x = -6, x = 4
• x = 6, x = -4
• x = 12, x = -2
• x = 8, x = -3

Solve the following quadratics equation by completing the square...

x² + 6x - 3 = 0

• x = -3 ± √12

• x = 3 ± √12

• x = 12 ± √3

• x = -12 ± √3

Solve the following quadratics equation by completing the square...

x² - 6x + 2 = 0

• x = -3 ± √7

• x = 3 ± √7

• x = 7 ± √3

• x = -7 ± √3

16a² - 9 = 0

solve using square root method

• a = ^-3/₄, ³/₄
