• 4

• 16

• 64

• -16

Find the missing value "c" to create a perfect square trinomial:
x² + 26x + ___ 

• 13

• 136

• 169

• 26

Factor: x² - 4x + 4

• (x + 2)²

• (x - 2)²

• (x + 4)²

• (x - 4)²

What value of c would make this a perfect square trinomial?
x² - 12x + c

• 36

• 24

• -36

Factor the perfect square trinomial:
x² + 16x + 64

• (x+8)²

• (x-8)²

• (x-4)²

• (x+4)²

Complete the square.
x² + 14x + ____

• x² + 14x - 196

• x² + 14x + 49

• x² + 14x - 49

• x² + 14x + 196

Complete the Square (this is step before you take square root on both sides)

x² + 6x = 5

• (x + 3)² = 5

• (x + 6)² = 9

• (x + 3)² = 14

• (x + 6)² = 14
