Cubic Equation Calculator

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.
To calculate the roots: For example ,Enter a=1, b=8, c=16 and d=10.

ax3 + bx2 + cx + d = 0
x³ + x² + x+ d = 0
