Homework Statement


Using method of frobenius about x=0 to solve:
(1-x) y''+xy'-\frac{\alpha^2}{x^2}+=0


Homework Equations


N/A

The Attempt at a Solution


1. plug in series into the equation.
2. adjust the index off all the terms.
3. write the extra terms separately so that we have all series starting at the same point.

and I get...

that the roots from the indicial equation
\lambda=\frac{1}{2}(1\pm\sqrt{4a^2+1})
and for the recursion I get
c_n=\frac{c_{n-1}(\lambda+n-1)(\lambda+n-2)-c_{n-2}(\lambda+n-2)}{(\lambda+k)(\lambda+n-1)-\alpha^2}

I am not sure how to check if this is correct or not.
Using a number for \alpha I don't get any nice series that has a function.

Sorry for the double post, first post was not showing.
 
There are two things I don't understand about this problem. First, when finding the nth root of a number, there should in theory be n solutions. However, the formula produces n+1 roots. Here is how. The first root is simply ##\left(r\right)^{\left(\frac{1}{n}\right)}##. Then you multiply this first root by n additional expressions given by the formula, as you go through k=0,1,...n-1. So you end up with n+1 roots, which cannot be correct. Let me illustrate what I mean. For this...
