Method of lobachevski for solving non linear algebraic equations with real coefficients

The method of Lobachevski permits to determine both real and complex roots of nonlinear algebraic equations with real coefficients. Its advantages are that it is not necessary to priory search the intervals of appurtenance of the roots, it simultaneously gives all the roots, reducing the computational time when using  other existing iterative methods, at last,  its reliability during operational works is easy.
