solve such problems require a lot of computations and par- tial fractions expansions. Therefore a more hands on approach is presented and discussed where the forms of the homogeneous and particular solutions are assumed, based on the pre- viously derived solutions. The homogeneous solution is determined by solving a characteristic equation, and using the characteristic roots together with the ass
