Question

Choose the product. -5p 3(4p 2 + 3p - 1) -20p 5 - 15p 4 + 5p 3 -20p 6 - 15p 4 - 5p 3 -20p 5 + 3p - 1 20p 5 + 15p 4 - 5p 3

Answer 1

-5p^3(4p^2 + 3p - 1) = -20p^5 - 15p^4 + 5p^3

answer is

A. first one
-20p^5 - 15p^4 + 5p^3

Answer 2

-5p^3(4p^2 + 3p - 1) = -20p^5 - 15p^4 + 5p^3

Explanation:

`-5p^3(4p^2 + 3p - 1)`

Distribute -5p^3 inside the parenthesis

-5p^3 times 4p^2 = -20p^5

-5p^3 times 3p = -15p^4

-5p^3 times -1 = 5p^3

Now we combine all the terms

`-5p^3(4p^2 + 3p - 1)=-20p^5 - 15p^4 + 5p^3`
