A Different Way to Solve Quadratic Equations
https://www.poshenloh.com/quadratic
Excerpt "I've recently been thinking about how to explain school math concepts in more thoughtful and interesting ways, while creating my Daily Challenge lessons. One night in September, while brainstorming different ways to think about the quadratic formula, I came up with a simple way to solve quadratic equations that I had never seen before. I was very surprised, as this method was easier to understand than what is typically written in textbooks. Adding this technique as a standard method would directly improve the learning experience for anyone trying to understand this topic, which is part of the regular mathematical curriculum everywhere in the world."
