integral of x(x^2-16)^2

\int x (x^{2} - 16)^{2} d x

\frac{x ^{6}}{6} - 8 x^{4} + 128 x^{2} + C

Solution steps

\int x (x^{2} - 16)^{2} d x

Expand

x (x^{2} - 16)^{2} : x^{5} - 32 x^{3} + 256 x

= \int x^{5} - 32 x^{3} + 256 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^{5} d x - \int 32 x^{3} d x + \int 256 x d x

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

\int 32 x^{3} d x = 8 x^{4}

\int 256 x d x = 128 x^{2}

= \frac{x ^{6}}{6} - 8 x^{4} + 128 x^{2}

Add a constant to the solution

= \frac{x ^{6}}{6} - 8 x^{4} + 128 x^{2} + C
