for which course did u apply at LSE,what grades?and r u gathered field?

u study at oxford???

fellow economist.

I saw tomthecool helped you with that particular question, however there is another method in order to do this question and seeing as you are doing edexcel C3 you will surely need to know this.
Here is a link on how to do the question using polynomial long divison if you haven't already learnt it http://en.wikipedia.org/wiki/Polynomial_long_division
You will find that if you do it correctly you will get q(x)=x^2 + 1 and r(x)=3 and so from doing this you can easily calculate that A=1 and B=3.
Hope this helps and good luck with the exam.

In response to your question (http://www.thestudentroom.co.uk/atta...d=1308503420):

Again, it's easy as long as you can spot a little trick...
Notice that:
(x^4+2)/(x^2-1) = (x^4-1)/(x^2-1) + 3/(x^2-1) = x^2+1 + 3/(x^2-1)

Why did I think to do this? Because the numerator of the fraction on the left was screaming "complete the square!" at me, but the numbers don't quite work! So I just split the fraction into two, so that I could complete the square -- then the answer followed easily.

But if you didn't spot this neat trick, then how could you do it? Well, it's a little harder, but make the right hand side of the equation into one fraction. then compare coefficients to get (I assume it will be) simultaneous equations for A and B.

Good luck in your exam
My younger sister is probably taking the same one, so I'm sure I'll hear all about how impossibly hard it was, and how badly she did

Ah well I wish you all the very best with that as I know that is tough for anyone, especially at the likes of oxford, lse and ucl.

Providing I get the right grades, I'm hoping to study Economics at either Oxford, lse, Ucl, SOas, queen mary's. I know they are all really tough but once I get my AS grades this summer, if they are a bit lower than expected than I'll remove either lse or Ucl. I'll ask my school about the AS further maths but yeh I hope that this will be allowed.

I'm pretty sure you can, but then again it all depends on your school/college. Different schools offer different modules and I know many further mathematicians who did FP1 and FP3, rather than FP2. I would have a word with your school and if you do have the choice, get a bit of detail on each module and see which inspires you because the FP modules don't inter link that well so it's not like in order to do FP3 you must do FP2.
What are you hoping to do at university and where are you hoping to go?

Also, can i do FP1, FP2 and M1 for AS Further Maths?

ok!
