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

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

2 e^{x} + \frac{x ^{3}}{3} + C

Solution steps

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

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

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

= 2 e^{x} + \frac{x ^{3}}{3}

Add a constant to the solution

= 2 e^{x} + \frac{x ^{3}}{3} + C
