I am new to Mathematica. I have entered a matrix multiplication and it gave me the answer back. However, the answer it gave back to me is not in the most reduced for it could be.
Ex. for one of the spaces I get a (1/2+Sqrt/2)^2+(-(1/2)+Sqrt/2)^2 but that is just 2.
How do I tell Mathematica to simplify even more?
