\begin{align} \int \left({a}{x^2} + bx + c\right) .dx\end{align}

Answer

\begin{align} \int \left({a}{x^2} + bx + c\right) .dx\end{align}

\begin{align} =a\int {x^2}.dx + b\int x.dx + c\int 1.dx \end{align}

\begin{align} =a\left(\frac {x^3}{3}\right) + b\left(\frac {x^2}{2}\right) + cx + C\end{align}
