$$\begin{pmatrix}-12&-22&19\\ -6&4&7\end{pmatrix}$$

Work Step by Step

Multiplying the matrices using the rules of matrices, we find: $$\begin{pmatrix}1\cdot \:0+\left(-4\right)\cdot \:3&1\cdot \:6+\left(-4\right)\cdot \:7&1\cdot \left(-1\right)+\left(-4\right)\left(-5\right)\\ 3\cdot \:0+\left(-2\right)\cdot \:3&3\cdot \:6+\left(-2\right)\cdot \:7&3\left(-1\right)+\left(-2\right)\left(-5\right)\end{pmatrix} \\ \begin{pmatrix}-12&-22&19\\ -6&4&7\end{pmatrix}$$
