Python-Pygame Lesson Quadratic (part 1) Solver and Grapher

David from Seattle Academy records some of his lessons for his students to review . This is a python lesson that I do with my Pre-Calculus and software development courses. The program will solve quadratic equations using the quadratic formula (part 1) and also test for imaginary solutions, give the vertex, symmetry line, and more (part 2). Parts 3 adds graph of parabola using pygame window display.
