    -2p^3 (2-p) (3p)

    Simplify:

    -2p^3 (2-p) (3p)

    How do you foil such an expression? Thanks.

    You have,
    -2p^3(2-p)
    Which is, open parantheses,
    -2p^3+2p^4
    But now you need to multiply by 3p,
    (-2p^3+2p^4)(3p)
    Open parantheses,
    -6p^4+6p^5

    (The way you open parantheses is multipling each term by the single term).

    When you open -2p^3(2-p), wouldn't that be -4p^3+2p^4?

    Let me try again:

    -2p^3 (2-p) (3p)

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

    -12p^4 + 6p^5

    Correct me if I am wrong. Thanks for showing me how.

    No, without you, I would have no clue on how to solve this problem.
