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

Answer:
[tex]6p^3+29p^2+22p-21[/tex]
Step-by-step explanation:
[tex](2p+7)(3p^2+4p-3)[/tex]
Multiply 2p+7 inside the parenthesis
first multiply 2p inside second parenthesis
[tex](2p)(3p^2+4p-3)=6p^3+8p^2-6p[/tex]
Now multiply 7 inside second parenthesis
[tex](7)(3p^2+4p-3)=21p^2+28p-21[/tex]
[tex](2p+7)(3p^2+4p-3)[/tex]
[tex]6p^3+8p^2-6p+21p^2+28p-21[/tex]
Combine like terms
[tex]6p^3+29p^2+22p-21[/tex]
