Summary
This article provides an intuitive, simple and computationally efficient method to solve for general quadratic equations compared to the traditional completing the square method. The only basic knowledge required for this purpose is the factoring/distributive property. Therefore, students can learn how to solve quadratic equations at an earlier stage without the need to memorize a formula.
Notes
1 The knowledge of Vieta’s formulas is not required. Also, Loh’s method does not rely on the theorem that two roots (counting multiplicity) always exist.
