Question

Consider the matrices.

Answer 1

The product matrix PQ can be found to be:

   $\left[\begin{array}{ccc}-17\\-3\\-37\\49\end{array}\right]$

How do you calculate the product matrix PQ?

The numbers on the first column of P will be multiplied by the first number of Q and the second column of P, by the second number in Q.

This becomes:

= $\left[\begin{array}{ccc}1(-1) + &2 (-8)\\3(-1) +&0 (-8)\\5(-1) +&4(-8)\\-1(-1) +&-6(-8)\end{array}\right]$

The result becomes:

= $\left[\begin{array}{ccc}-17\\-3\\-37\\49\end{array}\right]$
