# Math Help - -2p^3 (2-p) (3p)

1. ## -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).

3. 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.

Yes, you seem to more this more than me.

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