Question
**Problem 7.1:** Find the GS of (with \( x > 0 \))

\[
x^2 y'' + xy' - 9y = 6(x^3 + x^{-3})
\]

In this problem, you are asked to find the general solution (GS) of a second-order linear differential equation. The equation involves derivatives of \( y \) with respect to \( x \) and is presented as:

- \( x^2 y'' \) is the second derivative term, multiplied by \( x^2 \).
- \( xy' \) is the first derivative term, multiplied by \( x \).
- \(-9y \) is the linear term, with a coefficient of \(-9\).
- The right-hand side of the equation is \( 6(x^3 + x^{-3}) \), which serves as a non-homogeneous part of the equation.

The condition \( x > 0 \) is specified, indicating the domain of interest for the solution.
