Roots of a Cubic Equation

The calculator solves for the roots of a cubic equation.  Enter values into the fields to form equation of the type

ax3 + bx2 + cx + = 0

and press 'calculate'. The roots are given in the form

m + ni

where i is the square root of -1. If n is not zero then the root is complex. If n is zero then the root is real.

Press "see graphical function" to display the graph for the function you input (requires Java).

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