You can put this solution on YOUR website! (X+3)^2=36
(X+3)(X+3)=36
X^2+6X+9=36
X^2+6X+9-36=0
X^2+6X-27=0
(X+9)(X-3)=0
X+9=0
X=-9 ANSWER.
X-3=0
X=3 ANSWER.
You can put this solution on YOUR website! Here's another way to do it: take the square root of both sides
So x+3 equals positive 6 or negative 6 so:
Evaluate x+3=6 Subtract 3 from both sides Evaluate the right side
So x=3
Evaluate x+3=-6 Subtract 3 from both sides Evaluate the right side
So our answer is:
x=3 or x=-9
