For this case we must find the product of the following expression:
-3x ^ 3 (-2x ^ 2 + 4x + 7)

We apply distributive property to the terms within parentheses:


(-3x ^ 3 * -2x ^ 2) + (- 3x ^ 3 * 4x) + (- 3x ^ 3 * 7) =

We take into account that:


- * - = +\\- * + = -

To multiply powers of the same base, put the same base and add the exponents.


6x ^ {3 + 2} -12x ^ {3 + 1} -21x ^ 3 =\\6x ^ 5-12x ^ 4-21x ^ 3

Answer:

Option B
