Warm Up: Completing the Square

Write in vertex form:

y = x² - 12x - 1

• y = (x - 6)² + 35

• y = (x - 6)² - 37

• y = (x - 6)² - 1

• y = (x - 6)² - 7

Complete the square.
x² + 6x + ____

• x² + 6x + 9
• x² + 6x - 36
• x² + 6x + 36
• x² + 6x - 9

If given the equation y = 3(x + 5)² - 4, what is the vertex of the parabola?

• (5, -4)

• (-5, -4)

• (-15, -4)

• (15, -4)

Write y = x² + 4x - 1 in vertex form.

• y = (x - 2)² + 5
• y = (x + 2)² - 5
• y = (x + 2)² - 1
• y = (x +2)² + 3
