Alright, I just got some ridiculously long five page answer that ended up with imaginary numbers as the answer.

I think the problem is a bit more simple than what I used that's usually a dependable program to figure out an answer...

Get rid of the square root sign and voila...

Which is the correct answer. Was my method unorthodox or a coincidence or what?

EDIT: This is not actually the right answer...the answer is x=4?

Someone help?
