That the general solution of this non-homogeneous equation is actually the general solution of the homogeneous equation plus a particular solution. I’ll explain what that means in a second. So let’s say that h is a solution of the homogeneous equation. And that worked out well, because, h for homogeneous. h is solution for homogeneous. There should be some shorthand notation for homogeneous

Nonhomogeneous differential equations are the same as homogeneous differential equations, except they can have terms involving only x (and constants) on the right side, as in this equation: You also can write nonhomogeneous differential equations in this format: y …
p is solution of the homogeneous equation. Therefore, this solution can be written as linear combinations of a pair of fundamental solutions, y 1, y 2 of the homogeneous equation, y −y p = c 1y +c 2y . Since for every y solution of L(y) = f we can ﬁnd constants c 1, c 2 such that the equation above holds true, we have found a formula for all solutions of the nonhomogeneous equation. This
