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

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

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

Solution steps

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

Apply Integration By Parts

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

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

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

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

Add a constant to the solution

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

\int (x + \frac{3 y}{x}) d x

\int \frac{1}{t} cos (t + 3) d t

\int 7^{2 x + 8} d x

\int e^{- e^{- x} - x} d x

\int x (x^{2} - 1) d x
