Question

Quadratic cccccccccccccccccccccccc

Answer 1

Answer: -3 and -17

Explanation:

When completing the square we add and subtract
`(b)/(2) ^2` in the form ax² + bx + c.

`(b)/(2) ^2 = (-6)/(2) ^2=(-3)^2=9`

x² - 6x - 8 = (x - __)² - __

(x² - 6x) - 8 = (x - __)² - __

(x² - 6x + 9) - 8 - 9 = (x - __)² - __

(x - 3)² - 17 = (x - __)² - __

The blanks are 3 and 17.
