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 4 x^{2} + 2 d x

\int \frac{sin ( x )}{cos ( 2 x ) cos ( x )} d x

\int 3 sin (3 x + 2) d x

\int \frac{2 x + 5}{x ^{2} + 5 x + 2} d x

\int 5 + 4 x - x^{2} + 4 d x
