It is analytically shown that the methods are the third order. Numerical comparisons among the proposed iterative methods, Chebyshev method, Halley method, and Chebyshev-Halley method show that the proposed methods are better in performance, in terms of succeeding in obtaining the root.otherChebyshev methodHalley methodChebyshev-Halley methodfree deriva- tive iterative methodnonlinear equationOther
