**Topic: Matrix Diagonalization**

### Determine Whether the Given Matrix A is Diagonalizable
If it is, find a diagonalizing matrix \( P \) and a diagonal matrix \( D \) such that \( P^{-1}AP = D \).

#### Given Matrix A:
\[ 
\begin{pmatrix}
1 & 2 & -2 \\
0 & 1 & 0 \\
0 & -1 & 2 
\end{pmatrix}
\]

#### Steps and Solution

1. **Determine Eigenvalues and Eigenvectors**:
   - Calculate the eigenvalues of matrix \( A \).
   - For each eigenvalue, find the corresponding eigenvectors.

2. **Form the Matrix P**:
   - Construct matrix \( P \) using the eigenvectors as its columns.

3. **Construct the Diagonal Matrix D**:
   - The diagonal entries of matrix \( D \) will be the found eigenvalues of \( A \).

#### Answer Choices:

- **Option A**: The matrix is diagonalizable.
  \[
  \{P, D\} = \{\}
  \]
  \emph{(Use a comma to separate matrices as needed.)}

- **Option B**: The matrix is not diagonalizable.

#### Interactive Component:
Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
