I think this is the right section for this question as i think you have to work with it algebraically. I'm really not sure what way to think about it. Could do with some help soon if possible:

Given that $\displaystyle \frac{2x^4-3x^2+x+1}{(x^2-1)}=(ax^2+bx+c)+\frac{dx+e}{(x^2-1)}$ find the values of the constants a, b, c, d and e. (4 marks)

Thanks in advance to those who help.
