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

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

\frac{x ^{3}}{3} + \frac{1}{2} e^{2 x} + C

Solution steps

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

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

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

= \frac{x ^{3}}{3} + \frac{1}{2} e^{2 x}

Add a constant to the solution

= \frac{x ^{3}}{3} + \frac{1}{2} e^{2 x} + C

\int x (x^{2} + 4)^{6} d x

\int (x^{2} - 7 x) d x

\int \frac{6 x}{x ^{2} - 1} d x

\int - \frac{x e ^{x}}{2} d x

\int 0.6 x d x
