## Horner's method

Horner's method is a algorithm to divide a polynom by (x-a) ( From wikipedia:[In mathematics, Horner's method is either of two things: (i) an algorithm for calculating polynomials, which consists of transforming the monomial form into a computationally efficient form;[2] or (ii) a method for approximating the roots of a polynomial. The latter is also known as Ruffini–Horner's method.])
