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?
