Approximate the eigenvalues of

The image shows a matrix \(\mathbf{A}\) defined as follows:

\[
\mathbf{A} = \begin{bmatrix} 
2 & 1 & -1 \\ 
-1 & 0 & 2 \\ 
0 & 2 & 3 
\end{bmatrix}
\]

This is a 3x3 matrix, meaning it has three rows and three columns. Each element within the matrix is a number, positioned where it corresponds to a specific row and column.

- The first row consists of the elements 2, 1, and -1.
- The second row consists of the elements -1, 0, and 2.
- The third row consists of the elements 0, 2, and 3.

Matrices like this one are fundamental in various fields of mathematics and engineering, including systems of linear equations, transformation of geometric objects, and more.
