15 sie 2023 · 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.
2 paź 2016 · What you need a formula for is the solution to the cubic equation: [itex]Ax^3 + Bx^2 + Cx + D = 0[/itex]. There is no obvious way that “completing the cube” makes the solution into a matter of just taking cube roots in the same way that “completing the square” solves the quadratic in terms of square roots.

In algebra, a cubic equation in one variable is an equation of the form in which a is not zero. The solutions of this equation are called roots of the cubic function defined by the left-hand side of the equation.
A cubic equation is an equation which can be represented in the form \(ax^3+bx^2+cx+d=0\), where \(a,b,c,d\) are complex numbers and \(a\) is non-zero. By the fundamental theorem of algebra , cubic equation always has \(3\) roots, some of which might be equal.
