integral of (2x^3+6e^x)

\int (2 x^{3} + 6 e^{x}) d x

\frac{x ^{4}}{2} + 6 e^{x} + C

Solution steps

\int 2 x^{3} + 6 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 2 x^{3} d x + \int 6 e^{x} d x

\int 2 x^{3} d x = \frac{x ^{4}}{2}

\int 6 e^{x} d x = 6 e^{x}

= \frac{x ^{4}}{2} + 6 e^{x}

Add a constant to the solution

= \frac{x ^{4}}{2} + 6 e^{x} + C
