21p3 + 8p2 + 3p4 - 8p


-21p5 + 8p4 - 3p

Answer 1

The correct answer is

-28p^5 -21p^4 + 7p^3

Answer 2

Answer: The required product is
`-28p^5-21p^4+7p^3.`

Step-by-step explanation: We are given to choose the correct product of the following :

`Q=-7p^3(4p^2+3p-1).`

To find the required product, we need to multiply the common term to all the terms within the bracket.

We have

`Q\\\\=-7p^3(4p^2+3p-1)\\\\=-28p^5-21p^4+7p^3.`

Thus, the required product is
`-28p^5-21p^4+7p^3.`
