Find each product, if possible.

$\left[\begin{array}{cc}0& 8\\ 3& 1\\ -1& 5\end{array}\right]\cdot \left[\begin{array}{ccc}3& 1& -2\\ 0& 8& -5\end{array}\right]$

Write the multiplication of first row of first matrix and each column of second matrix and perform addition between the multiplications to form the first row of product matrix.

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

Write the multiplication of second row of first matrix and each column of second matrix and perform addition between the multiplications to form the second row of product matrix

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

Write the multiplication of third row of first matrix and each column of second matrix and perform addition between the multiplications to form the third row of product matrix

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

Perform simplification of obtained matrix.
