# Cubic Equation Calculator

To calculate the roots for given values in the equation ax^{3} + bx^{2} + cx + d = 0.

For example ,Enter a=1, b=8, c=16 and d=10.

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.
