Complete the Square

How would you rewrite this as a perfect square?

x² -14x + 49

• (x - 7)²

• (x - 14)²

• (x + 7)²

• (x + 14)²

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 y = 3x²+ 6x - 5 to vertex form.

• y = 3(x + 1)² - 8

• y = 3(x - 1) ² - 8

• y = 3(x + 2)² - 8

• y = 3(x - 2)² - 8
