YOUR FACE IS FUNNY :D (the picture). uhm so.... this is pretty self explanatory. what's the problem?
@amistre64  what about this. it has points .-.

anonymous · Answer

i dont know how this got posted, i was just reading this question earlier on google o.O

anonymous · Answer

still need the question answered though

anonymous · Answer

............ more name dropping sigh. go lookup remainder theorem. this is pretty straightforward

anonymous · Answer

i did...i tried my part in figuring out the answer and now im asking for help..jeez

anonymous · Answer

anonymous · Answer

explains it well

anonymous · Answer

okay well part 2 is what i need

anonymous · Answer

well .... it tells you the zeros of a function, that's why it's useful :P

I can help ya.

@RONNCC go sit in the corner -_-'

parthkohli · Answer

The remainder theorem says that if $n$ is a zero, then $P(n)=0$.

parthkohli · Answer

So is $P(2) = 0$?

anonymous · Answer

i just need Part 2 @ParthKohli :)

parthkohli · Answer

The part two will be something along the lines of:

"The remainder theorem is useful for finding zeroes because..."

anonymous · Answer

that much i know :P ...i need the rest of it

parthkohli · Answer

It saves the time of doing all that factoring and tricky stuff.
