Question

What is the product? [1 3 1 -2 1 0] [ 2 -2 3 5 4 1]

Answer 1

Answer:

   $AB = \left[\begin{array}{ccc}15&14\\-1&9\\\end{array}\right]$

Step-by-step explanation:

Explanation:-

Given matrix

      AB  =             $\left[\begin{array}{ccc}1&3&1\\-2&1&0\\\end{array}\right]$  $\left[\begin{array}{ccc}2&-2\\3&5\\4&1\end{array}\right]$

multiplication of two matrices

              $AB = \left[\begin{array}{ccc}1X 2+3X3+1X4&1X-2+3X5+1X1\\-2X2+1X3+0X4&-2X-2+1X5+0X1\\\end{array}\right]$

              $AB = \left[\begin{array}{ccc}2+9+4&-2+15+1\\-4+3+0&4+5+0\\\end{array}\right]$

           $AB = \left[\begin{array}{ccc}15&14\\-1&9\\\end{array}\right]$
