Step-by-step explanation:
 
        
             
        
        
        
The solution depends on the value of 

. To make things simple, assume 

. The homogeneous part of the equation is

and has characteristic equation

which admits the characteristic solution 

.
For the solution to the nonhomogeneous equation, a reasonable guess for the particular solution might be 

. Then

So you have


This means


and so the general solution would be
