To find the eigenvalues and eigenvectors of matrix $A$, let's analyze the matrix shown in the image:

$A = \begin{bmatrix} -1 & 2 & -2 \\ 1 & 2 & 1 \\ -1 & -1 & 0 \end{bmatrix}$

Step 1: Find the Eigenvalues

To find the eigenvalues, we need to solve the characteristic equation: $\det(A - \lambda I) = 0$ where $\lambda$ is the eigenvalue, and $I$ is the identity matrix.

1. Set up the matrix $A - \lambda I$: $A - \lambda I = \begin{bmatrix} -1 - \lambda & 2 & -2 \\ 1 & 2 - \lambda & 1 \\ -1 & -1 & -\lambda \end{bmatrix}$

2. Calculate the determinant of this matrix and set it equal to zero: $\det(A - \lambda I) = 0$

Step 2: Solve for Eigenvectors

Once we find each eigenvalue $\lambda$, substitute it back into $(A - \lambda I) \vec{x} = 0$ to solve for the corresponding eigenvectors.
