integral of x-x^4

Solution

\int x - x^{4} d x

Solution

\frac{x ^{2}}{2} - \frac{x ^{5}}{5} + C

Solution steps

\int x - x^{4} 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 d x - \int x^{4} d x

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

\int x^{4} d x = \frac{x ^{5}}{5}

= \frac{x ^{2}}{2} - \frac{x ^{5}}{5}

Add a constant to the solution

= \frac{x ^{2}}{2} - \frac{x ^{5}}{5} + C
