integral of (e^{2x}+e^x)

\int (e^{2 x} + e^{x}) d x

\frac{1}{2} e^{2 x} + e^{x} + C

Solution steps

\int e^{2 x} + e^{x} d x

Apply the Sum Rule:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int e^{2 x} d x + \int e^{x} d x

\int e^{2 x} d x = \frac{1}{2} e^{2 x}

\int e^{x} d x = e^{x}

= \frac{1}{2} e^{2 x} + e^{x}

Add a constant to the solution

= \frac{1}{2} e^{2 x} + e^{x} + C
