2. Find the LU factorizations of the matrices:

\[
\begin{bmatrix}
2 & 0 & 5 & 2 \\
-6 & 3 & -13 & -3 \\
4 & 9 & 16 & 17
\end{bmatrix}
\]

and

\[
\begin{bmatrix}
2 & 3 & 2 \\
4 & 13 & 9 \\
-6 & 5 & 4
\end{bmatrix}
\]

The task involves decomposing each matrix into the product of a lower triangular matrix (L) and an upper triangular matrix (U).
