Quadratic Functions
The name Quadratic comes from "quad" meaning square, because the variable gets squared (like x2).
It is also called an "Equation of Degree 2" (because of the "2" on the x)
Quadratics come in different forms! Even Hidden forms!
x2 = 3x -1- This is in hidden form
In standard form it would be x2 - 3x + 1 = 0
