how to solve a quartic equation. 2 Use variable change z x m x. The equation that must be solved to make it factorable is called the resolvent cubic.
A Modern Vision Of The Work Of Cardano And Ferrari On Quartics Solving Quartics Through Ferrari S Technique Mathematical Association Of America from www.maa.org
Bringing it down to a depressed quartic Start with the equation Divide both sides by a. There are many ways to solve quadratics. To the quartic equation 1 to obtain.
There are three main ways to solve quadratic equations.
The roots will be y 1 s p s2 4u 2. Unlike quadratic cubic and quartic polynomials the general quintic cannot be solved algebraically in terms of a finite number of additions subtractions multiplications divisions and root extractions as rigorously demonstrated by Abel Abels impossibility theorem and GaloisHowever certain classes of quintic equations can be solved in this manner. If you want to know how to master these three methods just follow these steps. The quartic can be solved by writing it in a general form that would allow it to be algebraically factorable and then finding the condition to put it in this form.
