Cubic equation - Wikipedia
Inflection points of a quintic function are the solution of a cubic equation (the second derivative set equal to zero).
The Cubic Formula - Vanderbilt University
I don't just mean that no one has found the formula yet; I mean that in 1826 Abel proved that there cannot be such a formula. The problem is that the functions don't do enough of what you need for solving all 5th degree equations.
4 Ways to Solve a Cubic Equation - wikiHow
2023年8月15日 · To solve a cubic equation, start by determining if your equation has a constant. If it doesn't, factor an x out and use the quadratic formula to solve the remaining quadratic equation. If it does have a constant, you won't be able to use the quadratic formula.

Solving Cubic Equations: Definitions, Methods and Examples
2024年4月28日 · The number of real solutions to the cubic equation is equal to the number of times the graph of the cubic equation crosses the X-axis. Example: Find the roots of equation f(x) = x 3 − 4x 2 − 9x + 36 = 0, using the graphical method.
Cubic Formula -- from Wolfram MathWorld
3 天之前 · The cubic formula is the closed-form solution for a cubic equation, i.e., the roots of a cubic polynomial. A general cubic equation is of the form z^3+a_2z^2+a_1z+a_0=0 (1) (the coefficient a_3 of z^3 may be taken as 1 without loss of generality by dividing the entire equation through by a_3).
complicated equations was the key to figuring out how to solve any cubic equation, and it was the cubic formula for these equations that lead to the discovery of complex numbers.
