Have you done this kind of problem before? What do you need to know to solve this one?
OpenStudy (anonymous):
I dont know nothing xD like i dont know how to solve or anything._. )

Better revise your thinking and attitude. Such negativism willo get you nowhere. If you're serious about wanting to solve this problem, share with me your thoughts about it. What does "completing the square" mean?
OpenStudy (anonymous):
I am not giving no attitude. I simply asked for help.
