integral of e^x+3x-x^2

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

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

Solution steps

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

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

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

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

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

Add a constant to the solution

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