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
