integral of-2+18x-12x^2

\int - 2 + 18 x - 12 x^{2} d x

- 2 x + 9 x^{2} - 4 x^{3} + C

Solution steps

\int - 2 + 18 x - 12 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 2 d x + \int 18 x d x - \int 12 x^{2} d x

\int 2 d x = 2 x

\int 18 x d x = 9 x^{2}

\int 12 x^{2} d x = 4 x^{3}

= - 2 x + 9 x^{2} - 4 x^{3}

Add a constant to the solution

= - 2 x + 9 x^{2} - 4 x^{3} + C
