Sum of two cubes: $a^3 + b^3 = (a+b) (a^2 -ab +b^2)$ difference of two cubes: $a^3 - b^3 = (a - b) (a^2 +ab +b^2)$

$ax^2 + bx + c = 0$ $x = frac{-b }{}$

A function $f$ is called even if $f(-x) = f(x)$ for all $x$ in the domain of $f$. A function $f$ is called odd if $f(-x) = -f(x)$ for all $x$ in the domain of $f$.

A wider parabola has a leading coefficient $a$ closer to 0.

* The graph of $y = -f(x)$ is the graph of $y=f(x)$ reflected across the X-axis. The graph of $y=f(-x)$ is the graph of $y=f(x)$ reflected across the Y-axis.
