Can some one solve this problem?

Question

Solve using matrix multiplication:
{1 2 3} {2 -1 0}
{2 -1 4} X {3 2 5}
{ 0 1 0} {-1 -2 1}

Answer 1

{1 2 3} {2 -1 0} = 1*2+2*(-1)+3*0 = 2-2+0 = 0
{2 -1 4} X {3 2 5} = 2*3+(-1)*2+4*5 = 6-2+20 = 24
{ 0 1 0} {-1 -2 1} = 0*(-1)+1*(-2)+0*1 = 0-2+0 = -2

This assumes the left factor is a row vector and the right factor is a column vector. If it's the other way around use http://www.analyzemath.com/matrixmultiplication/matrixmultiplication.html

If this is one problem of a 3x3 matrix times a 3x3 matrix, then the answer is by rows:

{5 -3 13}
{-3 -12 -1}
{3 2 5}

Answer 2

???
There are several ways to interpret your notation. Is it 3 seperate problems, or are you trying to show a pair of 3x3 matrices to be multiplied, or what?
