Please see the attached file.

1) xy"-(x+2)y'+2y=0.....(1)

Solution:
Write the given equation as
Comparing it with , we get
Since xP(x) and x2Q(x) are both analytic at x=0, so x=0 is a regular singular point of (1).

Let the series solution of (1) be,
...(2)

Substituting these values in (1), we get

...(4), which is an identity.
Making the coefficient ...
