    Evaluate products of expressions

    I have an exercise in my Algebra book which asks me the following:

    Evaluate the products of the following expression:

    3x2(-4xy3)(-6x2y2)
    I am not really sure how to do this, because I am multiplying polynomials. Can anyone please help me out with this one?

    Re: Evaluate products of expressions

    Hello, kkm!

    Evaluate: . 3x^2(\text{-}4xy^3)(\text{-}6x^2y^2)

    I am not really sure how to do this, because I am multiplying polynomials. . . . . no
    Can anyone please help me out with this one?

    If you are confused at this level, you may need more help than we can offer.

    There are no polynomials is this problem.


    We have: . 3\cdot x^2\cdot(\text{-}4)\cdot x \cdot y^3\cdot(\text{-}6)\cdot x^2 \cdot y^2

    . . . . . . =\;(3)(\text{-}4)(\text{-}6)\cdot (x^2)(x)(x^2)\cdot(y^3)(y^2)


    Can you finish it now?

    Thanks from kkm

    Thank you for clarifying my mistake, Soroban.

    Is the end result: 72x2xy3y2 ?

    Where could I get a refresh on this topic on the Internet? I think I am lacking basic knowledge to solve these kind of problems.
