Inhomogeneous Linear Second-Order Equations

If the given second-order ODE is inhomogeneous, DSolve applies the method of variation of parameters to return a solution for the problem.
This solves an inhomogeneous linear second-order ODE. The solution is composed of two parts: the first part is the general solution to the homogeneous equation, and the second part is a particular solution to the inhomogeneous equation.
