The answer is $=((5,1),(-5,19))$

let's do the matrix multiplication
You multiply horizontally for the first matrix and vertically for the second matrix.

$((0,2,1),(-5,-1,0),( , ,))$ $((1,-4, ),(0,1, ),(5,-1, ))$

$=((0+0+5,0+2-1),(-5+0+0,20-1+0))$

$=((5,1),(-5,19))$

How do you multiply ((0, 2, 1), (-5, -1, 0))((0, 2, 1), (-5, -1, 0)) with ((1, -4), (0, 1), (5, -1))((1, -4), (0, 1), (5, -1))?
