(3 points) Let $A = \begin{bmatrix} 1 & 0 & 0 \\ 6 & -1 & 6 \\ 3 & -1 & 4 \end{bmatrix}$. Find an invertible matrix $P$ and a diagonal matrix $D$ such that $D = P^{-1}AP$. $P = \begin{bmatrix} 0 & & \\ 1 & & \\ 1 & & \end{bmatrix}, D = \begin{bmatrix} 5 & 0 & 0 \\ 0 & -1 & 0 \\ 0 & 0 & \end{bmatrix}$

Find an invertible matrix P such that P-1 AP is a diagonal matrix, where A = (3 2 2 0)
By computing the eigenvalues and eigenvectors of A = (3 -2 1 0), find a matrix P such that P^(-1)AP = D where D is a diagonal matrix. Use this diagonalization to compute A^6.
