Answer
$\begin{bmatrix} -6 &8\\4&2\end{bmatrix} $
Work Step by Step
Two matrices can be subtracted together if they have the same dimensions.
The subtraction is done by simplify substracting each element of the subtrahend from the corresponding element of the minuend.
Thus, we have:
$\begin{bmatrix} -6 & 8\\0&0\end{bmatrix} -\begin{bmatrix} 0 &0\\-4&-2\end{bmatrix} =\begin{bmatrix} -6-0&8-0\\0-(-4)&0-(-2)\end{bmatrix} =\begin{bmatrix} -6 &8\\4&2\end{bmatrix} $
Therefore, the difference of two matrices is: $\begin{bmatrix} -6 &8\\4&2\end{bmatrix}.$
