Find the Matrix Product When Possible $A = \left[ \begin{array} { r r } 2 & - 2 \\ - 4 & - 5 \end{array} \right]$

Find the matrix product when possible.
-Given $A = \left[ \begin{array} { r r } 2 & - 2 \\ - 4 & - 5 \end{array} \right]$ , find $A ^ { 2 }$ .

A)
$$\left[ \begin{array} { r r } - 4 & - 14 \\- 28 & - 17\end{array} \right]$$
B)
$\left[ \begin{array} { r r } 12 & 6 \\ 12 & 33 \end{array} \right]$
C)
$\left[ \begin{array} { r r } 4 & 4 \\ 16 & 25 \end{array} \right]$

D)

$$\left[ \begin{array} { r r } 8 & 2 \\41 & 0\end{array} \right]$$
