Matrix B

[ -2 1 0 1]

[ 3 0 2 1]

[ -1 1 2 -1]

[ 3 -2 1 0]

I need to find the products of AB and BA, if possible.

Being that both matrices are 4x4's I have concluded that matrix A x B and B x A are both possible. Would appreciate help and an explanation, Thanks!!!

P.S. Sorry if the matrices are sloppy, not entirely sure on how to type an complete solid matrix, sorry!
