Question

Find the product. -3x^ 3(-2x^ 2 + 4x + 7)

6x6 - 12x4 + 21x3
6x5 - 12x4 - 21x3
6x5 + 12x4 + 21x3

Answer 1

w

Explanation:

w is the answer to all ur problems

Answer 2

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
