We calculate a complex system of linear equations of this form We write all the elements in the input field. It does not store any personal data.Root-finding algorithms for common roots of several multivariate polynomialsĪ system of polynomial equations (sometimes simply a polynomial system) is a set of simultaneous equations f 1 = 0. Easy Equation Solver is a simple and easy to use program for solving equations. As you can see, the data can be not only numeric but also be an arbitrary expression that includes complex numbers. , f h = 0 where the f i are polynomials in several variables, say x 1. , x n, over some field k.Ī solution of a polynomial system is a set of values for the x is which belong to some algebraically closed field extension K of k, and make all equations true. A complex number can be represented in the form of a+bi, which is the combination of both the real numbers and the imaginary numbers. When k is the field of rational numbers, K is generally assumed to be the field of complex numbers, because each solution belongs to a field extension of k, which is isomorphic to a subfield of the complex numbers. Here, a and b are real numbers and i is the imaginary number. A quadratic equation is an equation, where atleast one term should. This article is about the methods for solving, that is, finding all solutions or describing them. As these methods are designed for being implemented in a computer, emphasis is given on fields k in which computation (including equality testing) is easy and efficient, that is the field of rational numbers and finite fields. Searching for solutions that belong to a specific set is a problem which is generally much more difficult, and is outside the scope of this article, except for the case of the solutions in a given finite field. The numerous singular points of the Barth sextic are the solutions of a polynomial systemĪ very simple example of a system of polynomial equations is For the case of solutions of which all components are integers or rational numbers, see Diophantine equation.
