Expert Solution

Product of 2 matrices;

$[\begin{matrix} 1 & - 1 \\ - 4 & 5 \end{matrix}] . [\begin{matrix} 3 & 0 \\ 1 & - 2 \end{matrix}] = [\begin{matrix} 1.3 + (- 1) (1) & 1.0 + (- 1) (- 2) \\ (- 4) (3) + (5) (1) & (- 4) 0 + (5) (- 2) \end{matrix}] = [\begin{matrix} 2 & 2 \\ - 7 & - 10 \end{matrix}]$

NOTE: PRODUCT OF 2 MATRICES CANBE EVALUATED BY MULTIPLYING ELEMENTS OF THE FIRST ROW OF THE FIRST MATRIX WITH THE FIRST COLUMN OF THE SECOND MATRIX THEN ADD ALL THE PRODUCT OF ELEMENTS. CONTINUE THIS PROCESS UNTIAL EACH ROW OF THE FIRST MATRIX MULTIPLIED WITH EACH COIUMN OF THE SECOND MATRIX
