@ehuman @Luigi0210 @happinessbreaksbones 
can either of you correct and check my answer?

usukidoll · Answer

for #1 it's the first choice...the numbers are right but the signs are wrong. you need to switch the signs on the result

anonymous · Answer

You also forgot to cancel one of the x's. (It's $x^3$ not $x^2$)
Also, I just noticed, why is this in Biology?

anonymous · Answer

ohh lol put it in the wrong section okay

usukidoll · Answer

anonymous · Answer

It's not that bad of a word problem, you just have to divide the polynomial by both things.
(That's the part that's bad)

usukidoll · Answer

sighhhhh kkkkkk

usukidoll · Answer

so it;s like two parts and then add them together ish

anonymous · Answer

Anyway since I'm lazy and hate synthetic division I expanded the given answer and it's wrong. I dunno which one is right though!

usukidoll · Answer

well multiple choice is awesome lol

usukidoll · Answer

it gives clues

anonymous · Answer

"Expanding 3 more polynomials" is pretty much right next to "Doing synthetic division" on my list of "Fun things," but yeah. :P

anonymous · Answer

Anyway! I think it's C.

usukidoll · Answer

I no like word problems wahhhh!!! at least I checked those four

anonymous · Answer

you agree @UsukiDoll and imma give the medal to @UsukiDoll because i said i was before we started this sorry @SACAPUNTAS but i will fan you

usukidoll · Answer

read more about switching signs when it comes to dividing polynomials. you got the numbers right, but the signs wrong

anonymous · Answer

ohh okay so 1.A 2.D 3.B 4.D 5.C?

anonymous · Answer

Also read about synthetic division if you haven't already. It is a lot less annoying. I mean, it's still pretty annoying, but it's more like a yipping dog instead of nails on a chalkboard.
