Another way to deal with multiple roots of nonlinear equations was created, which were not well resolved by other methods. Newton’s method is a fundamental and significant method that use to finding multiple roots. This research presents a variety of two-step methods as another adjustment of Newton’s method for finding multiple roots of nonlinear equations with unidentified multiplicity m. A few examples were given to show the efficiency of the new methods using Schroder’s method, Halley’s method, Dong method and Li et al. (2009) method. The method is particularly suitable for finding multiple roots of nonlinear equations and to give comparison which method is the best.
