Hey, this is actually a College class but im not very good at math so Im in an Intermediate Algebra, I still think it most likely goes here but, anyway... I missed a lecture on some of this and while I managed to learn a majority of the chapter myself im stuck on a few problems. I simply dont even understand how to start them.

Find the product - Rational Expressions/Equations

(Sofar I canceled ad, and 3b but thats about all I got)

ac + 3a +2c +6......ad - 5a + 2d - 10

--------------- X -----------------

ad + a + 2d + 2......bc + 3b - 4c - 12

Find the quotient - Rational Expressions/Equations

(I flipped the second fraction in both already, they were originally division but thats about all I got)

4a³ - 8a².....5a^4

--------- X -------

.....15a......3a² - 6aThose three I am really having trouble with. Sorry if I posted them wrong, I couldnt get the math code to work. I tried making them as readable as possible.y² + y - 20...........y

----------- X --------------

......7x²........3y² + 19y + 20

Thanks
