Question

One can check that λ = 5, 1 are eigenvalues of B.

If possible, diagonalize matrix B or explain why B is not diagonalizable.

The matrix \( B \) is given as:

\[
B = \begin{bmatrix}
2 & 2 & -1 \\
1 & 3 & -1 \\
-1 & -2 & 2 
\end{bmatrix}.
\]

This matrix \( B \) is a 3x3 matrix, which means it has 3 rows and 3 columns. Each entry in the matrix is a real number, and they are arranged in a specific order as shown. 

In this matrix:
- The first row is \([2, 2, -1]\),
- The second row is \([1, 3, -1]\),
- The third row is \([-1, -2, 2]\).

Matrices like this are used in various areas of mathematics and applied sciences, such as solving systems of linear equations, transformations in geometry, and more.
