$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
Roots of $ax^2+bx+c=0$. Discriminant $D=b^2-4ac$ determines nature.
Key Concepts
Understand it beyond memorising formulas
Functions
A function maps each input to exactly one output. Written $f:A\to B$. Domain, codomain, and range must be clearly identified. Composite: $(g\circ f)(x)=g(f(x))$.
