Lets say you have the linear differential equation $y'' + y =3x$;

The associated homogeneous equation is $y'' + y = 0$

The set of the solutions to the homogeneous equation is {$\alpha \cos +\beta \sin ; \alpha, \beta \in \Bbb R$}.

One particular solution to the innitial equation is 3x.

Thus theset of solutions to the initial equation is {$\alpha \cos x +\beta \sin x + 3x; \alpha, \beta \in \Bbb R$}.
