![**Finding the Characteristic Polynomial of a 3x3 Matrix**
To find the characteristic polynomial of the matrix, use either a cofactor expansion or the special formula for 3x3 determinants. Note that finding the characteristic polynomial of a 3x3 matrix is not straightforward with just row operations due to the involvement of the variable λ.
Matrix:
\[
\begin{bmatrix}
3 & 0 & 0 \\
-2 & 2 & 3 \\
2 & 0 & 5
\end{bmatrix}
\]
**The characteristic polynomial is** [Insert polynomial here].
