Factoring Completing the Square

Solve by factoring: x² + 3x - 18 = 0

• x = -3 and x = 6

• x = 3 and x = -6

• x = -9 and x = 2

• x = 9 and x = -2

Complete the square for

x² - 12x + ____

• 144

• 36

• - 36

• 24

Given the perfect square trinomial, identify the equivalent expression

• (x-18)²

• (x-9)²

• (x+81)²

• (x+9)²

Solve

(x+6) (x-4) = 0

• x = -6, x = 4

• x = 6, x = -4

• x = 12, x = -2

• x = 8, x = -3

• 
• 
• 
• 

Write the following quadratic expression in completed square form... x² + 4x + 10

• (x + 4)² + 6

• (x + 2)² + 6

• (x + 4)² - 6

• (x + 2)² - 6

• A
• B
• C
• D

Solve by completing the square:
k² − 12k + 23 = 0

• {6 + √13, 6 - √13}

• {-6 + √13, -6 - √13}

• {6 + √59, 6 - √59}

• {-6 + √59, -6 - √59}

Which would be a correct step while using completing the square to solve the equation shown:

• (x + 3)² = 5

• (x + 6)² = 9

• (x + 3)² = 14

• (x + 6)² = 14

Find the value of "c" that completes the square. Then rewrite the trinomial as a perfect square.
