There is no difference between "-x2" and "-(x2)"; they mean the same thing.From what I understand there's a difference of opinions when it comes to this. Some people look at it as -(x^2) and others -x^2. Both give different answers which is why I'm asking what should I do when I have something like in front of me?
No; "-x2" means "the negative of the square of x", or "-[(x)(x)]". On the other hand, "(-x)*(-x)" means "the square of negative x", or "(-x)2 = (-1)(-1)(x)(x) = (+1)(x2) = x2".Wouldn't -x2 mean -x * -x...?
