[Computational Complexity] The Quadratic Formula
- A few weeks ago my eighth-grade daughter learned about the quadratic formula for solving ax2+bx+c=0. She's impressed I can still rattle it off like a song "Negative bee plus or minus the square root of bee squared minus for-ay-see all over two-ay". She then asked the question I love to hear, "How did anyone come up with that formula?" So I decided to show her how to derive it but couldn't figure it out on the spot. How embarrassing! I did manage to figure it out later and showed her the next day.Her textbook gives conditions to use the quadratic formula.
