“…This technique has extensively been used to develop some useful algorithms for solving nonlinear equations [4,5,10,18]. In 2015, Noor et al [18], using the same decomposition technique along with the idea of coupled system, proposed two fourth-order iterative methods ( [18], Algorithms 2.12 and 2.13) with efficiency index of 1.2600 each. In this work, using the quadrature formula along with the fundamental law of calculus, truncating the series of ( ) at quadratic level and decomposition technique of [5], we construct a family of new iterative methods for solving nonlinear equations.…”
