For years and years of teaching advanced mathematics, I always just found the vertex of a parabola by completing the square. In challenging top end students, I'd give them "raunchy" x-intercepts and have them find the vertex. I taught the algorithm in this product, and figured that every textbook would do the same. I used to have dozens of old Algebra 2 and Pre-Calculus textbooks. The step by step procedure was not in any of them. I hope that all of you who teach HONORS level mathematics will
