Question
I'm currently facing difficulties in solving this problem using matrix notation alone, and I'm looking for your help. The requirement is to find a solution using matrix notation exclusively, without utilizing any other methods. Could you kindly provide me with a comprehensive, step-by-step explanation using matrix notation to guide me towards the final solution?
![### Eigenvalues and Eigenvectors Calculation
#### Problem Statement
1. **Find the eigenvalues and eigenvectors of the matrix \( A \):**
\[
A = \begin{pmatrix}
0 & 4 & 12 \\
0 & -4 & -12 \\
5 & 8 & 8
\end{pmatrix}
\]
#### Additional Tasks
- **If \( A \) is diagonalizable, find a matrix \( P \) and a diagonal matrix \( D \) such that \( P^{-1}AP = D \).**
- **If \( A \) is diagonalizable, calculate \( A^9 \begin{pmatrix} 1 \\ 0 \\ 2 \end{pmatrix} \).**
#### Detailed Steps
1. **Find the eigenvalues:**
- Solve the characteristic equation \( \text{det}(A - \lambda I) = 0 \).
2. **Find the eigenvectors:**
- For each eigenvalue \( \lambda \), solve \( (A - \lambda I)\mathbf{v} = 0 \) for the vector \( \mathbf{v} \).
3. **Diagonalization:**
- If the matrix \( A \) is diagonalizable, express it in the form \( P^{-1}AP = D \), where \( D \) is a diagonal matrix containing the eigenvalues and \( P \) is a matrix whose columns are the corresponding eigenvectors.
4. **Computing \( A^9 \):**
- If \( A \) is diagonalizable and we know its diagonal form \( D \), compute \( A^9 \) using \( A = PDP^{-1} \), then calculate \( A^9 \begin{pmatrix} 1 \\ 0 \\ 2 \end{pmatrix} \).
This problem requires knowledge of linear algebra concepts including eigenvalues, eigenvectors, matrix diagonalization, and matrix exponential computations.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4bed6ad9-30ab-4f7a-8335-3ed0abd0b992%2F6495af2d-7eaa-4d6a-8329-39f390aa1f4a%2Fbaed2dr_processed.jpeg&w=3840&q=75)
