Let $f(x)=x^2$
When $a \ne 0$, there are two solutions to
$ax^2 + bx + c = 0$
and they are
$x = \dfrac{-b \pm \sqrt{b^2-4ac}}{2a}$.
\(x = \dfrac{-b \pm \sqrt{b^2-4ac}}{2a}\).
$\int \limits _a^b x^2\;\mathrm{d}x= \dfrac{1}{3} x^3 \Big|_a^b$
$A = \left ( \dfrac{1}{2} \sum \limits _{n=0}^x{\left. a^x \middle \vert b^x \right.}\right ) + c^x$
