integral of 5x^3-2x

Solution

\int 5 x^{3} - 2 x d x

Solution

\frac{5 x ^{4}}{4} - x^{2} + C

Solution steps

\int 5 x^{3} - 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 5 x^{3} d x - \int 2 x d x

\int 5 x^{3} d x = \frac{5 x ^{4}}{4}

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

= \frac{5 x ^{4}}{4} - x^{2}

Add a constant to the solution

= \frac{5 x ^{4}}{4} - x^{2} + C
