Cubic Equation Calculator
To calculate the roots for given values in the equation ax3 + bx2 + 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
ax3 + bx2 + 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.
