The solution to the equation,

Is given by

Here you have the equation,

Thus you need to find a particular solution.
By inspection it is easy to see that works.

Thus, the full solution is

this is a second grade ordinary differential equation and you solve it by getting the characteristic equation which in this case is:



then

(+ or - )

and then you gotta use the standard solutions for complex numbers and u will get:



but this is the general solution of the eq. so u gotta apply the parameters variation method or the undefined coefficient method to get the particular solution or also by inspection as the mod said
