Multiply the following polynomials and write the resulting polynomial in descending order. (3x-8)(2x^2+4x-9)

The product of the polynomial will be:
(3x-8)(2x^2+4x-9)
=3x(2x^2+4x-9)-8(2x^2+4x-9)
=6x^3+12x^2-27x-16x^2-32x+72
=6x^3-4x^2-59x+72

The  6x^3-4x^2-59x+72

A. is the answer in this question
