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

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

2 (\frac{1}{4} x^{4} (3 x^{4} - 5) - \frac{3 x ^{8}}{8}) + C

Solution steps

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

Take the constant out:

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

= 2 \cdot \int x^{3} (3 x^{4} - 5) d x

Apply Integration By Parts

= 2 (\frac{1}{4} x^{4} (3 x^{4} - 5) - \int 3 x^{7} d x)

\int 3 x^{7} d x = \frac{3 x ^{8}}{8}

= 2 (\frac{1}{4} x^{4} (3 x^{4} - 5) - \frac{3 x ^{8}}{8})

Add a constant to the solution

= 2 (\frac{1}{4} x^{4} (3 x^{4} - 5) - \frac{3 x ^{8}}{8}) + C
