integral of (3-x^2)

Solution

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

Solution

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

Solution steps

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

\int 3 d x = 3 x

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

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

Add a constant to the solution

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