Solve by completing the square:

n² - 2n - 3 = 0

• n = 3 and -1

• n = 4 and -4

• n = 5 and -3

• n = 8 and -7

Solve by completing the square:

x² + 10x = -9

• x = 1 and -12

• x = -1 and -9

Solve by completing the square:

k² − 12k + 20 = 0

• k = 10 and 2

• k = -6 and -6

• k = 22 and -10

• k = -2 and 6

Solve by completing the square (lead number must be 1):

4x² - 32x + 8 = 12

• x = 8.12 & -0.12

• x = 8.12 & 0.12

• x = -8.12 & 0.12

• x = -8.12 & -0.12

Convert to vertex form: y = x² + 8x + 2

• y = (x + 4)² - 14

• y = (x + 4)² - 6

• y = (x + 4)² - 18

• y = (x + 4)² + 6

Convert to vertex form: y = x² - 2x + 5

• y = (x - 1)² + 4

• y = (x - 1)² - 4

• y = (x - 1)² + 3

• y = (x - 1)² + 7
