Quartic Equation Solver
This page contains a routine that solves a Quartic Equation.
Once the problem is arranged into the following form (a, b, c, d, and e are known constants), the equation can be solved for values of x that satisfy the equation.
a x 4 + b x 3 + c x 2 + d x + e = 0
Since the equation is a fourth degree equation (the equation's highest power is four), there will be four solutions.
Input the values for a, b, c, d, and e below, and then click the "Calculate Solutions" button to have the results calculated.
NOTE: The solutions may include a non-zero imaginary component, as indicated by the "i" field.
Also, note the Error Code output.
