In my literature reviews I found a few things that I can't quite understand.
I have the following equation:

I'm told that by using the eigenvalue factorization:

, I can change the first equation to:

2. The attempt at a solution
I tried changing Equation 2 to just be (A^T)A and then subbing into the first equation, but I can't quite do anything with those inverses.
Also, what does the exponent of '-2' mean in the context of a 4x4 matrix? Lastly, what is matrix U?
Thank you!
