Research of Newton method to solve the real root of the polynomial equation

摘要

Real coefficient polynomial equation for the root of the problem was studied in the paper in order to solve the problem of the unary real coefficient polynomial equation root calculation. The novel practical numerical solution method was proposed to get the root of the unary real coefficient polynomial equation and general Newton iterative method was improved and perfected. Meanwhile, the method of getting the root of more than 5 times polynomial equation in the whole real domain roots was studied. In the end, results show that the methods proposed is effective in solution of the iteration rapidly.
