 All you had to do is ask! They said, "Let S … be written as 1/P−1/Q". That simply means they want you to rewrite S in the form 1/P−1/Q. In other words, what do the polynomials P and Q need to be, so that: 1/P − 1/Q = 2x/(1 − x^2) Yes, but note the grouping symbols added in red. (These are needed, when typing numerators or denominators that contain more than one term.) Also, please use symbols as given: S, x, P, Q (not Sinf, X, p, q). That's not a correct method for decomposition. Did you google for any lessons or examples, as suggested? (Maybe you're just guessing.) Click to expand... I did, and yeah I should elaborate more. Anyway, thank you

I did [look at a lesson] …
Very good. Can you try again, using the method you saw?

Ah, I didn't realize that you were done. It's good forum etiquette to finish threads (eg: post a final answer or statement).

Cheers!
