Given the equation y = -2(x + 3)² + 8, identify the vertex.

• (3, 8)

• (-2, 3)

• (-3, 8)

• (-2, -3)

x² - 12x - 3 = 0

To solve this equation by completing the square, identify the correct step in the process.

• x² -12x + 36 = 3

• (x - 3)² = 6

• (x - 6)² = 3

• (x - 6)² = 39

• (x - 3)² = 39
