# Polynomials HELP!! plzz watch

1. Divide (x^3 + 2x^2 -3) by (x-1)

It would be really helpful if you could show me how to get to the answer! I've got a rough idea of what to do but keep getting stuck on the same bit on this particular question.

cheeeeers

Post your current working and where you get stuck, people here won't give you just an answer they wanna see a genuine attempt at working it out :[
3. (x-1) ... (x^2 +3x... and then what do i do? :PP
4. Did you remember to write in the 0x bit? I find thats the main thing that stumps people.
5. If you need help with how do do polynomial long division, look here:

http://en.wikipedia.org/wiki/Polynomial_long_division The example includes the "0x" idea.

What particular bit is causing problems?

Show your working and where you're stuck.
6. loool

(x^3 + 2x^2 -3)/(x-1)

how can you get a x^3 term from (x-1) times by x^2 so x^2(x-1)=x^3-2x^2

thats first term of your solution xd

Are you sure? x²(x-1) equalled x³ - x² when I was at school.

And please try not to laugh at other people's questions...as the joke could end up being on you.

If you really need the answer, ignore that because it is also wrong.

I wouldn't normally give an answer, but feel it's necessary here.

It divides exactly and the quotient (answer) is x²+3x+3

Therefore x³+2x²-3 = (x-1)(x²+3x+3)

My bad, just realised I wrote a minus instead of a plus at the end I feel like a pleb.
11. Thanks guys for your efforts
