Quadratic Formula

For any equation $ax^2 + bx + c = 0$:

$$x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$

Simultaneous Equations

Given $2x + 3y = 12$ and $x - y = 1$, substitution into the first equation yields a unique solution for both $x$ and $y$.

Law of Cosines

Finding an unknown side in any triangle:

$$c^2 = a^2 + b^2 - 2ab\cos(C)$$
