Solving equations with the steps for the elimination method will really be useful for your algebra exam. This method makes use of the fact that the solution of an equation is not changed if we multiply both sides of the equation by the same factor. This method generalizes to systems with additional variables (see "elimination of variables" below, or the article on elementary algebra.) In algebra, a quadratic equation (from the Latin quadratus for "square") is any equation that can be rearranged in standard form as ax²+bx+c=0 where x represents an unknown, and a, b, and c represent known numbers, where a ≠ 0. Das gaußsche Eliminationsverfahren oder einfach Gauß-Verfahren (nach Carl Friedrich Gauß) ist ein Algorithmus aus den mathematischen Teilgebieten der linearen Algebra und der Numerik.Es ist ein wichtiges Verfahren zum Lösen von linearen Gleichungssystemen und beruht darauf, dass elementare Umformungen zwar das Gleichungssystem ändern, aber die Lösung erhalten.
