Using the Least Squares Method with Five Points to Solve Algebraic Equations Nonlinear

Abstract

In this paper, we introduce an extension of previous research to estimate the parameters of nonlinear algebraic models using the least square method to find the roots of nonlinear algebraic equations that is an important problem in science and engineering later many methods have developed for solving nonlinear equations. The Least square method for five points is used to find the present methods (PM). We applied a number some examples and numerical results obtained show that the present method is faster or slowest than the other methods with the higher degrees of least square polynomial.
