Evaluate the expression \(\displaystyle - 8 A - 8 B\)
\begin{equation*} A = \left[\begin{matrix}-5 & -5 & 3 & 4\\2 & 8 & -8 & 8\\6 & -7 & 6 & 0\\0 & 0 & -6 & -5\end{matrix}\right], \text{ and } \quad\quad B = \left[\begin{matrix}-7 & -6 & -7 & -8\\7 & -4 & -9 & -2\\-5 & -6 & 5 & -6\\-4 & 4 & -3 & 1\end{matrix}\right] \end{equation*}

The sum is \(\displaystyle \left[\begin{matrix}96 & 88 & 32 & 32\\-72 & -32 & 136 & -48\\-8 & 104 & -88 & 48\\32 & -32 & 72 & 32\end{matrix}\right]\).
