(A) To multiply the two matrices,we perform row-by-column multiplication:$\left[\begin{array}{cc}2 & 1 \ 3 & 2 \ -1 & 1\end{array}ight] 	imes \left[\begin{array}{ccc}1 & 0 & 1 \ -1 & 2 & 1\end{array}ight]$$= \left[\begin{array}{ccc}2(1)+1(-1) & 2(0)+1(2) & 2(1)+1(1) \ 3(1)+2(-1) & 3(0)+2(2) & 3(1)+2(1) \ -1(1)+1(-1) & -1(0)+1(2) & -1(1)+1(1)\end{array}ight]$$= \left[\begin{array}{ccc}2-1 & 0+2 & 2+1 \ 3-2 & 0+4 & 3+2 \ -1-1 & 0+2 & -1+1\end{array}ight]$$= \left[\begin{array}{ccc}1 & 2 & 3 \ 1 & 4 & 5 \ -2 & 2 & 0\end{array}ight]$

Compute the indicated product: $\left[\begin{array}{cc}2 & 1 \\ 3 & 2 \\ -1 & 1\end{array}\right] \times \left[\begin{array}{ccc}1 & 0 & 1 \\ -1 & 2 & 1\end{array}\right]$
