Question
![**Problem 1:**
Let \( A = \begin{pmatrix} 2 & 2 \\ 3 & 1 \end{pmatrix} \). Does there exist an invertible matrix \( P \) such that
\[ P^{-1}AP = \begin{pmatrix} 2 & 0 \\ 0 & 3 \end{pmatrix} \]?
**Discussion:**
This problem involves determining if the matrix \( A \) can be diagonalized. The goal is to find an invertible matrix \( P \) such that the matrix \( P^{-1}AP \) is diagonal. This would imply that \( A \) is similar to a diagonal matrix, specifically \( \begin{pmatrix} 2 & 0 \\ 0 & 3 \end{pmatrix} \).
For a matrix \( A \) to be diagonalizable, it must have distinct eigenvalues and a sufficient number of linearly independent eigenvectors to form the matrix \( P \). This transformation essentially rotates and scales the linear transformation described by \( A \) into a simpler diagonal form.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F0780f626-a981-4f24-912b-c0e4a815959e%2F6a2cec71-5cde-4549-a937-1093b3834487%2F7jyhmkm_processed.png&w=3840&q=75)
