Expert Solution

Step 1

Consider the given matrix :

$A = [\begin{matrix} 2 & 3 & - 1 \\ 1 & 1 & 1 \\ 1 & 1 & 2 \end{matrix}] B = [\begin{matrix} 1 & 1 & 1 \\ 1 & 2 & 3 \\ 3 & 2 & 0 \end{matrix}]$

Using the matrix calculator to present the results as stated

AB= $[\begin{matrix} 2 & 6 & 11 \\ 5 & 5 & 4 \\ 8 & 7 & 4 \end{matrix}]$

$A^{- 1} = [\begin{matrix} - 1 & 7 & - 4 \\ 1 & - 5 & 3 \\ 0 & - 1 & 1 \end{matrix}]$
