Thread: next section of review: dividing polynomials

1. 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:
$
(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, $8x^4y^3-6y^8$

right?

yeah, that's it

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
