Finding a general solution of cauchy-euler equation

Question

Assignment:

Find a general solution of the Cauchy-Euler equation. Assume x > 0.

1] 3x²y" - 4xy' + 2y = 0     

2] 2x²y" - 7xy' + 7y = 0     

3] 9x²y" - 9xy' + 10y = 0     

4] x²y" - 5xy' + 10y = 0

5] 4x²y" + y = 0

6] x²y" + 7xy' + 9y = 0

Provide complete and step by step solution for the question and show calculations and use formulas.
