Roots of a Quintic Equation


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

ax5 + bx4 + cx3 + dx2 + ex + f = 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).

x5   +   x4   +   x3   +   x2   +   x   +     =  0  
ax5   +   bx4   +   cx3   +   dx2   +   ex   +   f   =  0
