Given Determine $C A - C B$
A) $\left[ \begin{array} { r r r } - 20 & - 22 & 32 \\ - 16 & - 14 & 40 \\ 0 & 6 & 24 \end{array} \right]$

Given:
$$A = \left[ \begin{array} { r r r } 4 & 2 & - 3 \\1 & - 2 & 2\end{array} \right] , B = \left[ \begin{array} { r r r } 0 & - 2 & 5 \\5 & 4 & 2\end{array} \right] , C = \left[ \begin{array} { r r } - 4 & 1 \\- 5 & - 1 \\- 3 & - 3\end{array} \right] ,$$
determine $C A - C B$ .

A) $\left[ \begin{array} { r r r } - 20 & - 22 & 32 \\ - 16 & - 14 & 40 \\ 0 & 6 & 24 \end{array} \right]$
B) $\left[ \begin{array} { r r r } - 16 & - 20 & 24 \\ - 4 & 6 & 0 \end{array} \right]$
C) $\left[ \begin{array} { c c } - 12 & 24 \\ 46 & 2 \end{array} \right]$
