HELP PLZ

What number needs to be added to both sides of the equation to complete the square? x^2+12x=-34

Answer 1

`36`

Explanation:

The first step in completing the square is moving 34 to the other side of the equivalent symbol, then use this formula:

`[(b)/(2)]^(2)`

`[(12)/(2)]^(2)= {6}^(2) = 36`

You will then have this in Vertex Form:

`{[x + 6]}^(2) - 70`

The −70 comes from what you deduct from 36 to get −34. Remember, in this formula,
`-H` gives you the OPPOSITE TERMS OF WHAT THEY REALLY ARE, while
`K` gives you the NORMAL TERM, so be EXTREMELY CAREFUL.

I am joyous to assist you anytime.

Answer 2

Answer: The answer to your question is: 36

Explanation:

x^2 + 12x + 6^2 = - 34 + 6^2

x^2 + 12x + 36 = -34 + 36

(x + 6)^2 = 2
