because This is the value that completes the square. However, since the entire square is multiplied by 9, this value must be multiplied by 9 before we can add it across the equals:

18 + 9 (9) = 9 (x² + 6x + 9)

18 + 81 = 9 (x² + 6x + 9)

99 = 9 (x² + 6x + 9)

Dividing both sides by 9, we have:

11 = x² + 6x + 9

11 = (x + 3) ²
