A
[ 1 0
-2 4
5 -1 ]
D
[ 5 -2 -1
4 3 1 ]
The first step in a problem like this is to make sure the matrices can actually be multiplied. Here we have a 3x2 * 2x3. The quick check is to make sure the inside numbers are the same. If they are, then the matrices can be multiplied.
The basic setup for this problem goes like this:
[ a b
c d
e f ]
*
[ g h i
j k l ]
= [ ag+bj ah+ak ai+al
cg+dj ch+dk ci+cl
eg+fj eh+fk ei+el ]
So, take it from there!
