If a polynomial P(x) has a root x=a, i.e., if P(a)=0, then x-a is a factor of P(x).

One of the operations of addition, subtraction, multiplication, division, and integer (or rational) root extraction.

A number which can be represented by a finite number of additions, subtractions, multiplications, divisions, and finite square root extractions of integers. Such numbers ...

An extension of the secant method of root finding to higher dimensions.

A root-finding algorithm also known as the tangent hyperbolas method or Halley's rational formula. As in Halley's irrational formula, take the second-order Taylor series ...

A finite extension K=Q(z)(w) of the field Q(z) of rational functions in the indeterminate z, i.e., w is a root of a polynomial a_0+a_1alpha+a_2alpha^2+...+a_nalpha^n, where ...

A field K is said to be algebraically closed if every polynomial with coefficients in K has a root in K.

The use of three prior points in a root-finding algorithm to estimate the zero crossing.

Newton's method, also called the Newton-Raphson method, is a root-finding algorithm that uses the first few terms of the Taylor series of a function f(x) in the vicinity of a ...

The necessary and sufficient condition that an algebraic curve has an algebraic involute is that the arc length is a two-valued algebraic function of the coordinates of the ...
