Factoring Quadratic Functions X Method

• Extracting the Root

• Factoring

• Completing the Square

• Quadratic Formula

• Because I can see the factors quickly

• Because a = 1 and b = even number

• Because the bx term is missing

• Because the equation is in Vertex Form

• Because it is messy and my last resort.

When factoring
x² - 4x + 4 = 20,
what goes in the blank?
(x - __ )² = 20

• 4

• 2

• 8

• 20

Solve by factoring. (HINT: Factor GCF 1st)

• x = 3, x = -6

• x = 0, x = 2

• x = 2, x = 3

• x = -2, x = 1

Solve for the values of x:
(x + 2)(x - 3) = 0

• { 2, 3 }

• { -2, -3 }

• { 2, 3 }

• { -2, 3 }

• -2, 4
• -8
• ±8
