Solve by Completing the Square: 2x²+4x-5=7 Hint: Move the 5 and you must have a lead number of 1!

• -0.4 and -3.4

• -2.3 and 4.3

• -3.6 and 1.6

• no solution

Complete the square for

x² + 12x + ____

(find the missing number in the blank)

• x² + 12x + 144

• x² + 12x + 36

• x² + 12x - 36

• x² + +12x - 144

Solve by completing the square 4x² - 32x + 8 = 12 (lead number must be 1!)

• x = 8.12 & -0.12

• x = 8.12 & 0.12

• x = -8.12 & 0.12

• x = -8.12 & -0.12

• x = -3 and 4

• x = 3 and 4

• x = -3 and -4

• x = -1 ± √6

• x = 1 ± √6

• x = 6 ± √1

• x = -6 ± √1

• (x + 3)² = 5

• (x + 6)² = 9

• (x + 3)² = 14

• (x + 6)² = 14

• x = 2 and -2
