I am going crazy. it is almost 3:00 in the morning and I have been trying to figure out a problem and I just can't get it.

If you could show me how I would so appreciate it. Iam taking an online math class and the teacher has 7 other classes and never seems to answer the questions on time. Thank you so much!

A =

- 2 0 1
- 2 -1 3
- 4 1 2

B =

- -2 1 0
- 4 3 -2
- 1 2 -1

I need to find (A + B)squared

2 + -2 0 + 1 1 + 0 is 0 1 1

and then squared is the same answer

The book has the answer as

Matrix

I know this is difficult to read but I hope you can understand it. i didn't know how to type any other way :(
