integral of 8x^3(2x^4+4)

\int 8 x^{3} (2 x^{4} + 4) d x

16 (\frac{1}{4} x^{4} (x^{4} + 2) - \frac{x ^{8}}{8}) + C

Solution steps

\int 8 x^{3} (2 x^{4} + 4) d x

Take the constant out:

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

= 8 \cdot \int x^{3} (2 x^{4} + 4) d x

x^{3} (2 x^{4} + 4) = 2 x^{3} (x^{4} + 2)

= 8 \cdot \int 2 x^{3} (x^{4} + 2) d x

Take the constant out:

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

= 8 \cdot 2 \cdot \int x^{3} (x^{4} + 2) d x

Apply Integration By Parts

= 8 \cdot 2 (\frac{1}{4} x^{4} (x^{4} + 2) - \int x^{7} d x)

\int x^{7} d x = \frac{x ^{8}}{8}

= 8 \cdot 2 (\frac{1}{4} x^{4} (x^{4} + 2) - \frac{x ^{8}}{8})

Simplify

= 16 (\frac{1}{4} x^{4} (x^{4} + 2) - \frac{x ^{8}}{8})

Add a constant to the solution

= 16 (\frac{1}{4} x^{4} (x^{4} + 2) - \frac{x ^{8}}{8}) + C
