integral of x^3-30x

Solution

\int x^{3} - 30 x d x

Solution

\frac{x ^{4}}{4} - 15 x^{2} + C

Solution steps

\int x^{3} - 30 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^{3} d x - \int 30 x d x

\int x^{3} d x = \frac{x ^{4}}{4}

\int 30 x d x = 15 x^{2}

= \frac{x ^{4}}{4} - 15 x^{2}

Add a constant to the solution

= \frac{x ^{4}}{4} - 15 x^{2} + C
