Expand not working
I multiplied some matrices, as seen in the picture to get a 1 by 1 matrix. I tried to expand the contents, but it didn't work. I had to copy and paste the contents. Why didn't it work?

You should give the full computation (definitions of
A
andx
) because this way the problem you encounter is not reproducible. Also, instead of a picture, you can put code in your question and format it using the button "101 010".
