Matrix A is factored in the form PDP-1 where

A = PDP^{^{-1}} = \begin{bmatrix} -2 & 0& -1\\ 0& 1 & 2\\ 1 & 0 & 0 \end{bmatrix} \begin{bmatrix} 3 &0 &0 \\ 0 & -2 &0 \\ 0 & 0 & -2 \end{bmatrix}\begin{bmatrix} 0 &0 &1 \\ 2&1 &4 \\ -1&0 &-2 \end{bmatrix}

1. what are the eigenvalues of A and what are the dimensions of the corresponding eigenspaces?
