The solutions to some kinds of secondorder non-homogeneous linear differential equations with variable coefficients were discussed by using constant coefficient method and invariant method. The advantages and disadvantages of the two methods were analyzed and compared, and the feasibility of the two methods was illustrated by a concrete example.

Key words: variable coefficients, solutions, non-homogeneous, differential equation
