In this article, by using the modified CK direct method, we give a relationship\nbetween the generalized fifth-order KDV equations with variable coefficients\nand the corresponding constant coefficients ones. Then, we construct the abundant\ntravelling solutions by the extended trial equation method (ETEM) in\nterms of different functions, such as the elliptic functions, rational functions,\nhyperbolic functions and trigonometric functions. The extended trial equation\nmethod is powerful and can be used to other partial differential equations\nand more research can be done by this method.
