Question

PLEASE HELP I WILL MARK YOU BRAINLIEST!!!! Determine the exact and approximate solutions for 9(x+4)^2=36 show your steps PLS HELP IM BEGGING

Answer 1

Answer:

x= -2, -6

Step-by-step explanation:

Divide both sides by 9

(x+4)^2=4

Take sqrt from both sides.

√(x+4)^2=√4

x+4= + or - 2

Because when taking √ of a perfect square it's gonna be + or -. Because -2 • -2 is 4. And 2•2 is also 4.

So you break it into two possible equations.

x+4=2 and x+4=-2

Subtract x from both sides on both equations

x=-2 x=-6

Hope this helps
