Oh, I didn't see your answer at the bottom, sorry. But yes, the answer you are getting is correct :)

vjt · Answer

here. (x-4)^2 = (x-4)(x-4) First: x * x = x^2 Outer: x *-4 = -4x Inner: x *-4 = -4x Last: -4*-4 =16 (x-4)^2 = x^2 - 8x + 16 https://answers.yahoo.com/question/index?qid=20110920201239AAd19sy
