Dude don't just look for the answer man it isn't going to help you in any way try to learn the concept. Ther's no point in just writing down answers without any clue of how to solve problems...

Look these problems are nothing too hard to understand if you try.
See identify the x coeffecient. Then just add square of half the coeffecient.
