Point 4 of 5

23.1.4 Spotting a, b, and c

Core idea

Tidy the expression into its standard shape and read off who is a, who is b, and who is c — and remember a can never be 0.

Module goal. Pick up the family of functions you've already met, get to know quadratics as a new member, and build their algebraic definition.
