For the differential equation


  


the method of undetermined coefficients works only when the coefficients a, b, and c are constants and the right‐hand term d( x) is of a special form. If these restrictions do not apply to a given nonhomogeneous linear differential equation, then a more powerful method of determining a particular solution is needed: the method known as variation of parameters
