Solving Quadratic Equations

This is a follow up to a previous post, Intercepts, The Zero Product Property, and Other Such Mathematical Disasters in which I wrote about some common misconceptions I was seeing in my students' work while I was grading a mid-unit quiz. I wanted to dive deep into what the root of the problem was, and … Continue reading Solving Quadratic Equations →

Intercepts, The Zero Product Property, and Other Such Mathematical Disasters

While grading the latest quizzes on quadratics, I discovered two conceptual misunderstandings that were emotionally triggering. The results I … Continue reading Intercepts, The Zero Product Property, and Other Such Mathematical Disasters →
