### Demonstrating the Cayley-Hamilton Theorem

The Cayley-Hamilton Theorem states that a matrix satisfies its characteristic equation. For example, the characteristic equation of the matrix shown below is as follows:

\[
A = \begin{bmatrix}
1 & -3 \\
2 & 5
\end{bmatrix}
\]

\[
\lambda^2 - 6\lambda + 11 = 0 
\]

and by the theorem you have

\[
A^2 - 6A + 11I = 0
\]

### Demonstrate the Cayley-Hamilton Theorem for the matrix \( A \) given below.

\[
A = \begin{bmatrix}
0 & 5 & -1 \\
-1 & 5 & -1 \\
0 & 0 & -1
\end{bmatrix}
\]

### STEP 1:
**Find and expand the characteristic equation.**

*Input area for characteristic equation expansion*

### STEP 2:
**Compute the required powers of \( A \).**

\[
A^2 = \begin{bmatrix}
\_\_ & \_\_ & \_\_ \\
\_\_ & \_\_ & \_\_ \\
\_\_ & \_\_ & \_\_
\end{bmatrix}
\]

\[
A^3 = \begin{bmatrix}
\_\_ & \_\_ & \_\_ \\
\_\_ & \_\_ & \_\_ \\
\_\_ & \_\_ & \_\_
\end{bmatrix}
\]

### STEP 3:
**Write a matrix version of the characteristic equation by replacing \( \lambda \) with \( A \). (Use \( I \) for the 3x3 identity matrix.)**

*Input area for matrix version of characteristic equation*

### STEP 4:
**Substitute the powers of \( A \) into the matrix equation from step 3, and simplify. Is the matrix equation true?**

*Yes*  
*No*
