## Teachers-and students-Guide to Everything Quadratic

**Details**: 100 pages

**Availability**: UNDER REVISION! Coming soon.

A comprehensive guide to everything one might ever want to do with quadratics in the standard high-school curriculum.

**PART I: The Algebra of Quadratics**

Don’t memorise the quadratic formula! That is way too hard and too far removed from true understanding!

(How about the cubic formula? We derive that too in this section – just for kicks.)

**PART II: Graphing Quadratics**

The easy way to graph quadratics.

The easy way to figure out a vertex without memorizing the vertex formula!

[And just for fun … How to graph complex roots!]

**PART III: Fitting Quadratics to Data**

Got three points? Want a quadratic to pass through them? Just write down the answer! (No fussing with calculators or messy systems of equations!)
