Description: This calculator computes real and complex roots for any quintic polynomial. It applies the Newton-Raphson Method, which iteratively finds an approximate root to the Quintic, starting out with a random initial guess. Then it factors the equation out to (x - r1)(ax4 + bx3 + cx2 + dx + e) and then solves the left-over Quartic Equation for roots 2 through 5.
