(x+1) ^2. So for this problem i learned the X factory in order to solve it. so what u. need to do is find a number(s) that multiply to 1. (the one on the far right is the one u multiply) and a those same numbers need to add to 2. so one and one multiply to one and add up to 2. so u do (x+1) (x+1) but since there the exact same u just put a little 2 up on the brackets
