The tool qcq.tbz contains routines to directly solve quadratic, cubic and quartic equations with real or complex coefficients (i.e., no iterative root finding). Examples where these root finders find utility is in direct, least-squares fitting of a parabola to noisy data, the intersection points of two conic sections, the distance of closest approach of two ellipses, and Alhazen's problem.
