Re: quadratic formula

The quadratic formula comes into its own when dealing with quadratic
functions that contain parameters; for example if you want to derive the
formula for the time a projectile is in the air, or if you want to study
families of functions. If students haven't developed to the point that
they can appreciate problems like this then they probably won't be able to
understand the value of the quadratic formula, and won't remember it.
Best,
