•  $x=64,\ \ x=-64$  

•  $x=1,\ \ x=-64$  

•  $x=16,\ \ x=-4$  

Solve using the square root property:
 $x^2-4=0$ 

•  $x=-2$  

•  $x=4,\ \ x=-4$  
  

•  $x=4$  

•  $x=2,\ \ x=-2$

Find the value that completes the square.

x² + 16x + _

• 16

• 8

• 64

• -8

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

• 4
• 2
• 8
• 20

Given the perfect square trinomial, identify the equivalent expression

x²-18x+81

• (x-18)²

• (x-9)²

• (x+81)²

• (x+9)²

Complete the Square

x² + 6x - 5 = 0

• (x + 3)² = 5

• (x + 6)² = 9

• (x + 3)² = 14

• (x + 6)² = 14

Simplify:
(3 + 2i) + (4i + 6)

• 9 + 6i
• 7i + 8
• 9 + 6i²
• 9 - 6i
