Please try again, keeping in mind that you can differentiate both sides of the power series expansion to obtain power series
representation for the derivative of the given function. So, to find the power series representation of a function of the form
a
(b+cx)2'
you may first find the power series representation of the function a. The resulting power series converges on the
same interval.
