Question

(Picture) MULTIPLYING POLYNOMIALS AND SIMPLIFYING EXPRESSIONS PLEASE HELP!!!!

Answer 1

`6p^3+29p^2+22p-21`

Explanation:

`(2p+7)(3p^2+4p-3)`

Multiply 2p+7 inside the parenthesis

first multiply 2p inside second parenthesis

`(2p)(3p^2+4p-3)=6p^3+8p^2-6p`

Now multiply 7 inside second parenthesis

`(7)(3p^2+4p-3)=21p^2+28p-21`

`(2p+7)(3p^2+4p-3)`

`6p^3+8p^2-6p+21p^2+28p-21`

Combine like terms

`6p^3+29p^2+22p-21`
