integral of 18-2x^2

Solution

\int 18 - 2 x^{2} d x

Solution

18 x - \frac{2 x ^{3}}{3} + C

Solution steps

\int 18 - 2 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 18 d x - \int 2 x^{2} d x

\int 18 d x = 18 x

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

= 18 x - \frac{2 x ^{3}}{3}

Add a constant to the solution

= 18 x - \frac{2 x ^{3}}{3} + C
