Hello all; having some trouble with these last homework questions!

Instructions: Find a power series representation for the function and determine the radius of convergence.

#1) f[x] = x^2/(1-2x)^2

Should I use partial fractions to split this up?

#2) Evaluate the indefinite integral as a power series. What is the radius of convergence. Integral of ArcTan(x^2)dx

Thanks so much for your help in the past and future all!
