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

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

\frac{4 x ^{3}}{3} + \frac{x ^{6}}{6} + C

Solution steps

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

Expand

x^{2} (4 + x^{3}) : 4 x^{2} + x^{5}

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

\int 4 x^{2} d x = \frac{4 x ^{3}}{3}

\int x^{5} d x = \frac{x ^{6}}{6}

= \frac{4 x ^{3}}{3} + \frac{x ^{6}}{6}

Add a constant to the solution

= \frac{4 x ^{3}}{3} + \frac{x ^{6}}{6} + C

\int 8 x (1 - x) d x

\int e^{t} cot (e^{t} - 8) d t

\int \frac{x ^{3}}{( x ^{4} + 9 ) ^{4}} d x

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

\int \frac{1}{2} x^{\frac{3}{2}} d x
