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 + 8x - 1

• y = (x + 4)² - 17

• y = (x + 4)² - 16

• y = (x + 4)² - 9

• y = (x + 4)² - 15

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

What do you do to the b value to correctly complete the square?

• square it
• divide it by 2 and square the result
• divide it by 2 and take the square root of the result
• divide it by 2 only
