You can't solve this. You only have one quantity. In order to solve it you must have one quantity equal to another quantity. You could factor this since it is the difference of two squares, but that isn't what you asked. Had you exerted a little more effort to explain where you were having difficulty, as the instructions for posting clearly tell you to do, I might have had a better chance of helping you.
