Answer:
[tex]16p^{3}-24p^{2} + 4p-40[/tex]
Step-by-step explanation:
Multiply each term from the first parantheses with each term in the second parantheses:
[tex]4p(4p^{2} + 2p + 5) -8(4p^{2} +2p+5)[/tex]
Distribute 4p and -8:
[tex]16p^{3}+8p^{2}+20p-32p^{2}-16p-40[/tex]
Collect like terms:
[tex]16p^{3} - 24p^{2} + 4p-40[/tex]
