Here is a link to the question:am studying for a Cal 2 final and I am having a lot of trouble with this one example. Find the power series representation for the function and the radius of convergence. I understand the concepts of power series representations and radii of convergence but I am not sure how to go about solving this problem. f(x) = 1/((2 + x)^2)

I've thought about maybe a partial fraction, but that wouldn't work, then I've thought about making this into f(x) = 1/4 * 1/1-(x^2 + 4x) and setting the x^2 and 4x to my a[n] function but I am not sure if this is correct or how to do it.

Help with this power series representation? - Yahoo! Answers

I have posted a link there to this topic so the OP can find my response.
