The quartic is the highest order polynomial equation that can be solved by radicals in the general case (i.e., one in which the coefficients can take any value).

- There is, in fact, a general formula for solving quartic (4th degree polynomial) equations. As the cubic formula is significantly more complex tha...
- Assuming the four roots $x_1$ , $x_2$ , $x_3$ , $x_4$ to be real, they are respectively $$x_1=-\frac{b}{4 a}-\frac{1}{2} \sqrt{\frac{\sqrt[3]{...
- Edited in response to Quonux's comments. Yes. As an answer I will use a shorter version of this Portuguese post of mine, where I deduce all the...
- There most certainly is, but it's ugly, complicated, and not worth memorizing. People know about it and have quoted or cited it for you, but really...
- We can reduce the problem of solving the general quartic to merely solving a quadratic . Given, $$x^4+ax^3+bx^2+cx+d=0$$ Then the four roots are,...
- Yes , there is a quartic formula. There is no such solution by radicals for higher degrees. This is a result of Galois theory, and follows from the...
- What has not been mentioned thus far is that one can in fact use any number of "auxiliary cubics" in the solution of the quartic equation. Don Herb...
- To your question, "if not, why not", I could say this (which I think goes a little further that the previous answers). A polynomial $p(x) \in \math...
- Regarding the inability to solve the quintic, this is sort-of true and sort-of false. No, there is no general solution in terms of $+$, $-$, $\tim...
In algebra, a quartic function is a function of the form. where a is nonzero, which is defined by a polynomial of degree four, called a quartic polynomial . A quartic equation, or equation of the fourth degree, is an equation that equates a quartic polynomial to zero, of the form. where a ≠ 0. [1]
4 days ago · A quartic equation is a fourth-order polynomial equation of the form z^4+a_3z^3+a_2z^2+a_1z+a_0=0. (1) While some authors (Beyer 1987b, p. 34) use the term "biquadratic equation" as a synonym for quartic equation, others (Hazewinkel 1988, Gellert et al. 1989) reserve the term for a quartic equation having no cubic term, i.e., a quadratic equation in x^2. Ferrari was the first to develop an ...
Mar 1, 2024 · What is a quartic function and its formula. How to factor and find its roots. Also, learn to graph it and find the domain, range, and zeros of it with examples.
A quartic equation is an algebraic equation of the form. These types of equations are extremely hard to solve; however, there are very clever methods for solving them by bringing it down to a cubic. I am going to list the simplest of the five. Also, if you only want the final results, the "TLDR" subsections give these results.
