You surely have some notes on this, or a chapter in your textbook that explains this? For really general questions like this, if you seriously can't find anything in your notes or textbook, its very simple to search terms like "monic" and "completing the square" into Google! We are here for specific help, when you are stuck on a question that you have given a serious attempt to!
