Show that the matrix is not diagonalizable.

\[ 
\begin{bmatrix} 
3 & -4 & 1 \\ 
0 & 3 & 1 \\ 
0 & 0 & 4 
\end{bmatrix} 
\]

**STEP 1:** Use the fact that the matrix is triangular to write down the eigenvalues. (Enter your answers from smallest to largest.)

\[ 
(\lambda_1, \lambda_2) = ( \_\_\_\_ , \_\_\_\_ ) 
\]

**STEP 2:** Find the eigenvectors \(\mathbf{x_1}\) and \(\mathbf{x_2}\) corresponding to \(\lambda_1\) and \(\lambda_2\), respectively.

\[ 
\mathbf{x_1} = \begin{bmatrix} \_\_ \\ \_\_ \\ \_\_ \end{bmatrix} 
\]

\[ 
\mathbf{x_2} = \begin{bmatrix} \_\_ \\ \_\_ \\ \_\_ \end{bmatrix} 
\]

**STEP 3:** Since the matrix does not have [Select] linearly independent eigenvectors, you can conclude that the matrix is not diagonalizable.
