integral of 16x(8x^2+2)^2

\int 16 x (8 x^{2} + 2)^{2} d x

16 (\frac{32 x ^{6}}{3} + 8 x^{4} + 2 x^{2}) + C

Solution steps

\int 16 x (8 x^{2} + 2)^{2} d x

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 16 \cdot \int x (8 x^{2} + 2)^{2} d x

Expand

x (8 x^{2} + 2)^{2} : 64 x^{5} + 32 x^{3} + 4 x

= 16 \cdot \int 64 x^{5} + 32 x^{3} + 4 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

= 16 (\int 64 x^{5} d x + \int 32 x^{3} d x + \int 4 x d x)

\int 64 x^{5} d x = \frac{32 x ^{6}}{3}

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

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

= 16 (\frac{32 x ^{6}}{3} + 8 x^{4} + 2 x^{2})

Add a constant to the solution

= 16 (\frac{32 x ^{6}}{3} + 8 x^{4} + 2 x^{2}) + C
