Chapter 3.1, Problem 27EQ

In Exercises 23-28, let

$A=\left[\begin{array}{ccc}1& 0& -2\\ -3& 1& 1\\ 2& 0& -1\end{array}\right]$

and

$B=\left[\begin{array}{ccc}2& 3& 0\\ 1& -1& 1\\ -1& 6& 4\end{array}\right]$

Use the row-matrix representation of the product to write each row of BA as a linear combination of the rows of A.
