Abstract
In this work, using a generalized ansatz, we have presented the extended tanh-method for constructing a variety of exact traveling wave solutions of the nonlinear diffusion reaction equation with quadratic, cubic and quartic nonlinearities. We have examined the density independent and dependent nonlinear diffusion reaction equation with a convective flux term and successfully obtain some new and more general solutions like kink and antikink solitons. The present work confirms the significant features of the employed method and shows the variety of the obtained solutions.
