You are correct. You would square both sides to eliminate the square root. Here is one way to do it.
Look at Rule 1 under the "distributing" section from this page
Square both sides
or
or
So the possible solutions are or
I'll leave the check to you to do. You need to plug each possible answer into the original equation and simplify. If you get a true statement, then the possible solution is a real solution. If not, then it's not a real solution.
