\item Qual o valor de x na equação abaixo?
$$15x + 132 = 25x +72$$
\begin{enumerate}
\item $x=6$
\item $x=7$
\item $x=8$
\item $x=9$
\item $x=10$
\end{enumerate}

Para toda equação do segundo grau na forma $ax^2 + bx + c = 0$, suas raízes são definidas por:
$$\dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}$$
\section{Definições Matemáticas}
\subsection{Definição de Derivada}
$$\dfrac{dy}{dx} = \lim_{h \to 0} \dfrac{f(x + h) - f(x)}{h} $$
\subsection{Definição de Integral}
$$\int_a^b f(x) dx = F(b) - F(a)$$
Este é um animal muito bacana

\begin{align*}
ax^2 + bx + c &= 0\\
ax^2 + bx &= -c\\
x^2 + \dfrac{bx}{a} &= \dfrac{-c}{a}\\ \\
x^2 + \dfrac{bx}{a} + \dfrac{b^2}{4a^2} &= \dfrac{b^2}{4a^2} - \dfrac{c}{a}\\ \\
\left(x+\dfrac{b}{2a}\right)^2 &= \dfrac{b^2 - 4ac}{4a^2}\\
x + \dfrac{b}{2a} &= \dfrac{\pm \sqrt{b^2 - 4ac}}{2a}\\
x &= \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}
