Question 102876: Tutor,
I was hoping you could help me with this problem. I can not seem to get it to check out and I am not sure where I am making the mistake.
Solve for X
x^2 + 4x + 4 = 7
I know I have the factor the left-hand side but I must be doing something wrong because it is not working out for me. Any help would be great. Thank you in advance for your time.

If you factor the left side you get:
.

.
Then if you take the square root of both sides you get:
.

.
Note the right side has a plus and minus sign. If you now subtract 2 from both sides
to get rid of the 2 on the left side you get:
