Question

In order to solve by completing the square, what value needs to be added to both sides of the equation:

Answer 1

The answer is "
`(x + 8)^2 = 58`"

Explanation:

Let the equation is:
`x^2+16x=-6`

by adding and subtracting 64 then:

`x^2 + 16x + 64 = -6 + 64\\\\x^2 + 2* x* 8 + 64 = -6 + 64\\\\ (x + 8)(x + 8) = 58\\\\ (x + 8)2 = 58`
