$[\begin{array}{c} - 9 & 2 \\ 3 & - 3 \end{array}] [\begin{array}{c} - 2 \\ 2 \end{array}]$

Step 1

Multiply each row in the first matrix by each column in the second matrix.

$[\begin{array}{c} - 9 \cdot - 2 + 2 \cdot 2 \\ 3 \cdot - 2 - 3 \cdot 2 \end{array}]$

Step 2

Simplify each element of the matrix by multiplying out all the expressions.

$[\begin{array}{c} 22 \\ - 12 \end{array}]$
