Alright, here is another question that I need some help with, I think I have an idea of how to do it but it never hurts to make sure, though
The question states:
solve the following equation.
My idea is to either, expand by minors, or, to evaluate it by using the main diagonals(?) method.
Which way would be quickest and easiest to do?
Or am I headed in the wrong direction entirely?
