WebDec 8, 2024 · The new process, developed by Dr. Po-Shen Loh at Carnegie Mellon University, goes around traditional methods like completing the square and turns finding roots into a simpler thing involving fewer steps that are also more intuitive. Here’s Dr. Loh's explainer video: Quadratic equations fall into an interesting donut hole in education. WebMay 16, 2024 · For Loh's method to be used, the quadratic must be of the form A x 2 + B x + C = 0 where A = 1. Certainly, if A ≠ 1 you can divide through by A and not affect the roots, but it means fractions, accompanying fraction arithmetic, and the possible need to rationalize denominators--all of which is not necessary if just using the commonly ... song homecoming on billions
