The calculator solution will show work using the quadratic formula to solve the entered equation for real and complex roots. Another program that I have put on Instructables is Herons Fo. The calculator solution will show work using the quadratic formula to solve the entered equation for real and complex roots. The Quadratic Formula is a milestone along the path to fully understanding algebra.
