Find the matrix product, if possible.

below.

Step-by-step explanation:

The number of columns in the first matrix must equal to the number of rows in the second for multiplication to be possible.

Here first matrix has 3 columns and second one has 3 rows so POSSIBLE.

[ -8 2 2]    { 3 }

                [ 0 ]

                [ -3]

=  -8*3  + 2*0 + 2 * -3 = [-30]  < Answer.

Note  a  1*3 matrix multiplied by a 1*3 matrix gives a 1*1 result.

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
