integral of x^4-2x

Solution

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

Solution

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

Solution steps

\int x^{4} - 2 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

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

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

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

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

Add a constant to the solution

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