The eigenvalues of a matrix are the solutions to the characteristic equation \( \det(A - \lambda I) = 0 \), where \( \lambda \) represents the eigenvalues.
To find the eigenvalues of the matrix, we need to solve the characteristic equation:
\[
\det(A - \lambda I) = 0
\]
Where \( A \) is the matrix, and \( I \) is the identity matrix. Solving for the eigenvalues will give us the answer.
