### Cubic Equation Calculator

Use this calculator to solve polynomial equations with an order of 3 (3rd Order Polynomial) such as

ax

^{3}+ bx

^{2}+ cx + d = 0, an equation that has into its terms one variable of the third degree is called the cubic equation. The discriminant tells the nature of the roots :

If more than zero, then equation has only one real root.

If less than zero, then equation has all real roots .

If equals to zero, then equation has real roots and all equal.
