## A Solver for a Cubic Equation

This page contains a routine that solves a Cubic Equation. It is written in JavaScript, so make sure that JavaScript is enabled in your browser.

Once the problem is arranged into the following form (**a**, **b**, **c**, and **d** are known *constants*), the equation can be solved for values of x that satisfy the equation.

**a** x ^{3} + **b** x ^{2} + **c** x + **d** = 0

Since the equation is a *third* degree equation (the equation's highest power is **three**), there will be **three** solutions, output as x_{1}, x_{2}, and x_{3}.

Input the values for **a**, **b**, **c**, and **d** below, and then click the "Calculate Solutions" button to have the results calculated.

**NOTE**: The solutions may include a non-zero imaginary component, as indicated by the "i" field.
