The modification of Halley’s method is divided into two cases. Both of modifications of Halley’s methods have order of convergence six and need four function evaluations per iteration. Furthermore, the computational results show that the method converges faster in obtaining a simple root of the nonlinear equations compared to Newton’s and Halley’s methodenNewton’s methodHalley’s methoda simple rootorder of convergenceArticle
