    It has been awhile since I've done this type of equation...I calculated it as x^2=13, if that helps.

    Don't forget to do this: from math import * because if you don't, you'll have to do math.sqrt(....), if you just use sqrt without that line, python thinks that you are using your own definition called sqrt.
