For the matrix \( A \), find (if possible) a nonsingular matrix \( P \) such that \( P^{-1}AP \) is diagonal. (If not possible, enter IMPOSSIBLE.)

\[
A = \begin{bmatrix} 
2 & 0 & 0 \\ 
2 & -2 & -1 \\ 
-1 & 0 & -2 
\end{bmatrix}
\]

\[ 
P = \begin{bmatrix} 
\Box & \Box & \Box \\ 
\Box & \Box & \Box \\ 
\Box & \Box & \Box 
\end{bmatrix} 
\]

Verify that \( P^{-1}AP \) is a diagonal matrix with the eigenvalues on the main diagonal.

\[
P^{-1}AP = \begin{bmatrix} 
\Box & \Box & \Box \\ 
\Box & \Box & \Box \\ 
\Box & \Box & \Box 
\end{bmatrix} 
\]
