better suggestion

Hi, I suggest that every time you post a question, you try posting all of the answers given to you. This way we will have a better solutions (shortcuts) for you. In thisp roblem you will be getting x^2 + 4x +4 + x^2 -2x + 4 = 2x^2 + 8 and then divide this answer by 2 to get (2x^2 +8)/2 = 2x^2/2 + 8/...
