![The problem asks to find an invertible matrix \( P \) and a diagonal matrix \( D \) such that \( P^{-1}AP = D \).
Given matrix \( A \):
\[
A = \begin{pmatrix}
11 & 0 & -6 \\
-12 & -2 & 6 \\
20 & 0 & -11
\end{pmatrix}
\]
Matrix \( P \) and matrix \( D \) are initially defined as:
\[
P = \begin{pmatrix}
0 & 0 & 0 \\
0 & 0 & 0 \\
0 & 0 & 0
\end{pmatrix}
\]
\[
D = \begin{pmatrix}
0 & 0 & 0 \\
0 & 0 & 0 \\
0 & 0 & 0
\end{pmatrix}
\]
To solve this problem, \( P \) needs to be found such that it is invertible, and \( D \) needs to be the resulting diagonal matrix after the transformation \( P^{-1}AP \). The task is to perform an eigenvalue decomposition or use another suitable method to determine \( P \) and \( D \).](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fec2b7ff9-b952-4215-9e0f-f264e2036fb8%2F50c74865-0e16-440f-8ab9-bfcf17fd88e4%2Fui69q6c_processed.png&w=3840&q=75)
