integral of x^2(2x^3+5)^4

\int x^{2} (2 x^{3} + 5)^{4} d x

\frac{16 x ^{15}}{15} + \frac{40 x ^{12}}{3} + \frac{200 x ^{9}}{3} + \frac{500 x ^{6}}{3} + \frac{625 x ^{3}}{3} + C

Solution steps

\int x^{2} (2 x^{3} + 5)^{4} d x

Expand

x^{2} (2 x^{3} + 5)^{4} : 16 x^{14} + 160 x^{11} + 600 x^{8} + 1000 x^{5} + 625 x^{2}

= \int 16 x^{14} + 160 x^{11} + 600 x^{8} + 1000 x^{5} + 625 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 16 x^{14} d x + \int 160 x^{11} d x + \int 600 x^{8} d x + \int 1000 x^{5} d x + \int 625 x^{2} d x

\int 16 x^{14} d x = \frac{16 x ^{15}}{15}

\int 160 x^{11} d x = \frac{40 x ^{12}}{3}

\int 600 x^{8} d x = \frac{200 x ^{9}}{3}

\int 1000 x^{5} d x = \frac{500 x ^{6}}{3}

\int 625 x^{2} d x = \frac{625 x ^{3}}{3}

= \frac{16 x ^{15}}{15} + \frac{40 x ^{12}}{3} + \frac{200 x ^{9}}{3} + \frac{500 x ^{6}}{3} + \frac{625 x ^{3}}{3}

Add a constant to the solution

= \frac{16 x ^{15}}{15} + \frac{40 x ^{12}}{3} + \frac{200 x ^{9}}{3} + \frac{500 x ^{6}}{3} + \frac{625 x ^{3}}{3} + C

\int cos (6 x) d x

\int (x^{5} + 1) e^{x^{6} + 6 x} d x

\frac{\partial}{\partial x} (x (x + 1)^{2})

n = 1 \sum \infty \frac{4}{n ^{2} + 5 n + 6}

\int \frac{sin ( \frac{9}{x} )}{x ^{2}} d x
