Oh, I think I can help you with this. :)
Here are the steps...
1. Isolate the terms with x variables. (Already done for you in this case)
2. Complete the square.
3. Balance the equation.
4. Factor the perfect square trinomial.
5. Solve for x by taking the sqrt of both sides and isolating x.

I'll guide you through the steps if you'd like...Let me know which one you are stuck on...:)
