**Writeacher**, Monday, April 18, 2011 at 7:19amWhat kind of HELP do you need? You need to be specific when asking questions here.

If all you do is post your entire assignment,**with no evidence of thinking on your part**, nothing will happen since no one here will do your work for you. But if you are specific about what you don't understand about the assignment or exactly what help you need, someone might be able to assist you.

**MathMate**, Monday, April 18, 2011 at 9:16amYou can simplify the problem to:

does A^2=(-A)^2?

The answer lies in how each element of A^2 is calculated, namely as the product of two elements of A.
