integral of (7x+e^{2x})

\int (7 x + e^{2 x}) d x

\frac{7 x ^{2}}{2} + \frac{1}{2} e^{2 x} + C

Solution steps

\int 7 x + e^{2 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 7 x d x + \int e^{2 x} d x

\int 7 x d x = \frac{7 x ^{2}}{2}

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

= \frac{7 x ^{2}}{2} + \frac{1}{2} e^{2 x}

Add a constant to the solution

= \frac{7 x ^{2}}{2} + \frac{1}{2} e^{2 x} + C
