Comment on A new way to make quadratic equations easyparent

Comments

this is not new

While the mathematician claims to not find historical evidence of this, it is suuuuper similar to something we went over in high school in Calculus. It was related to finding the vertex of a parabola and noting the roots will be equally distant to both sides of the mid point. At the time, it was used as a "see? Neat. It all works out" type lesson.

This was around 2001.
