    Since you say this is a homework problem, you really shouldn't ask for all the steps. What have you tried? Where are you getting stuck? Do you know what "completing the square" means? What difficulty are you having applying that method? The more information you give about your problem, the more helpful people will want to be, and, quite possibly, the more you will learn.2011-04-01
