Abstract
This article discusses the optimal second derivative-free iterative method to solve
nonlinear equations obtained by approximating the second derivative of the Noor-
Noor-Momani method using quadratic and cubic polynomials. Analytically, this
iterative method has an order of convergence four and its efficiency index is 1.5874.
The computational test shows that the resulting method can be used as an alternative
method for solving nonlinear equations.
