Hi,

The question asks:

[tex]f(x) = \frac{5x^{2} - 3x - 20}{x^{2} - 2x - 3}[/tex]

Find:

[tex]f^{(n)}(x)[/tex]

I try to find its rule, but I fail:

I have:

[tex]f'(x) = \frac{-7x^{2} + 10x - 31}{(x^{2} - 2x - 3)^{2}}[/tex]

And I have f''(x) is some kind of very very complicated number. What should I do in this kind of problem??

Any help will be appreciated,

Viet Dao,
