integral of 3x^2-x^3

Solution

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

Solution

x^{3} - \frac{x ^{4}}{4} + C

Solution steps

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

\int 3 x^{2} d x = x^{3}

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

= x^{3} - \frac{x ^{4}}{4}

Add a constant to the solution

= x^{3} - \frac{x ^{4}}{4} + C
