Answer

\[ \begin{bmatrix} 5 & -12 \\ 9 & -6 \end{bmatrix} \]

Work Step by Step

\[ \begin{bmatrix} -3 & 4 \\ 5 & 2 \end{bmatrix} \cdot \begin{bmatrix} 1 & 0 \\ 2 & -3 \end{bmatrix} = \begin{bmatrix} (-3 \cdot 1) + (4 \cdot 2) & (-3 \cdot 0) + (4 \cdot (-3) \\ (5 \cdot 1) + (2 \cdot 2) & (5 \cdot 0) + (2 \cdot (-3)) \end{bmatrix} \] \[ = \begin{bmatrix} -3 + 8 & 0 - 12 \\ 5 + 4 & 0 - 6 \end{bmatrix} \] \[ = \begin{bmatrix} 5 & -12 \\ 9 & -6 \end{bmatrix} \]
