When $a \ne 0$, there are two solutions to $(ax^2 + bx + c = 0)$ and they are

Inline math spanned over multiple lines: $\log xy = \log x + \log y$

Display math spanned over multiple lines:

Let $U$ be an open subset of the complex plane $\mathbb{C}$, and suppose the closed disk $D$ defined as

is completely contained in $U$. Let $f: U\to\mathbb{C}$ be a holomorphic function, and let $\gamma$ be the circle, oriented counterclockwise, forming the boundary of $D$. Then for every $a$ in the interior of $D$,

• $E = mc^2$
• $a^2 + b^2 = c^2$

1. $V - E + F = 2$
2. $i^2 = -1$

The Butcher tableau for this ERK method is
