A Year of Nights of Wondering IV: The Long and Sour of It All

I was attempting to “sell” the method of completing the square for solving quadratic equations.  I first square rooted both sides of an equation and solved.  Next I multiplied everything out and solved the same equation by factoring.  I labeled the first method “short and sweet” and as I started to label the second, “long”, Bethanie blurted “What? Long and sour?” I and the class laughed but she had made my point. I promised to write about it in this blog, but in hindsight I should also have said, “Long yes but as to sour I think that is a matter of taste.”
