Table of Contents. A calculator for the solutions of the general cubic equations is presented at the bottom of the page. We also present the formulas that give the solutions to the general cubic equation that has the form: \[ A x^3 + B x^2 + C x + D = 0 \] This equation can be solved using Cardano's method; but we first requires converting it into a depressed cubic (one without an \(x^2\) term).
The calculator will find the roots of the cubic equation in both the analytic and the approximate forms. Enter a cubic equation: For example, x^3-5x^2-3x+7=0 or x^3+1=5x^2 .
Free Cubic Equation Calculator - Solves for cubic equations in the form ax 3 + bx 2 + cx + d = 0 using the following methods: 1) Solve the long way for all 3 roots and the discriminant Δ 2) Rational Root Theorem (Rational Zero Theorem) to solve for real roots followed by the synthetic div/quadratic method for the other imaginary roots if applicable.
The Cubic Equation Calculator helps you solve cubic equations of the form: a x 3 + b x 2 + c x + d = 0 ax^3 + bx^2 + cx + d = 0. where: a a, b b, c c, and d d are real coefficients of the equation. x x represents the variable, and the calculator provides up to three real or complex solutions for x x.

How to Solve Cubic Equations? The traditional way of solving a cubic equation is to reduce it to a quadratic equation and then solve it either by factoring or quadratic formula. Like a quadratic equation has two real roots, a cubic equation may have possibly three real roots. But unlike a quadratic equation, which may have no real solution, a ...
It must have the term in x 3 or it would not be cubic but any or all of b, c and d can be zero. The solutions of this cubic equation are termed as the roots or zeros of the cubic equation. All third degree polynomial equations will have either one or three real roots. Solve the roots of the third degree equation using this cubic equation ...
