In this paper, we first present a fifth-order iterative method, which
is a variant of the double-Newton’s method. Based on this new method,
we propose a ninth-order iterative method. In contrast to the double-
Newton’s method, the ninth-order method only needs one additional
function evaluation per iteration, but the order of convergence increases
five units. Numerical examples are given to show the efficiency of the
presented methods.
