Analytically by using Taylor expansion and geometric series, the proposed Newton- Jarratt’s method have an fifth order of convergence with efficiency index 1.495. Numerical computations of several examples with some other discussed methods show that the proposed method in general has the smallest error in its approximation root of the nonlinear equations.enNewton-Jarratt’s methoditerative methodanalysis of convergencenonlinear equationsArticle
