    next section of review: dividing polynomials

    I have a bunch of problems like this on my review, and I can't remember how to do them:
    <br />
(32x^6y^4-24x^2y^9+4x^2y) DIVIDED BY (4x^2y)



    How would I do this? I think the + and - signs within the first set of parenthesis throw me off...

    just divide each term by 4x^2y separately and piece them together

    and don't forget what we learned here

    oooh yeah that makes sense to do it separate like that

    so, 8x^4y^3-6y^8

    oooh, yeah I need to add +1

    so, 8x^4y^3-6y^8+1

    right?

    ok sweet.


    so how would I do a problem like this?


    15m^3+26m^2-11m-6
    ___________________
    5m-3



    I'd know how to do it if it was just divided by 5m, but what do I do with the negative 3? For example, let's say I split it up, and the first section is

    15m^3
    ___________________
    5m-3


    that part would be 3m^2 something, but then what would I do with that negative 3?

    for this problem you have to use long division or synthetic division.

    i am way too tired to go through that right now. consult you textbook or the internet, or wait for someone else to help you
