Abstract

In the present paper we show that the Steffensen method for solving the scalar equation \(f\left( x\right) =0\), applied to equation
\[
h\left( x\right) =\tfrac{f\left( x\right) }{\sqrt{f^{\prime}\left( x\right) }}=0,
\]
leads to bilateral approximations for the solution. Moreover, the convergence order is at least 3, i.e. as in the case of the Halley method.
