integral of 12+x-x^2

Solution

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

Solution

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

Solution steps

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

\int 12 d x = 12 x

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

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

= 12 x + \frac{x ^{2}}{2} - \frac{x ^{3}}{3}

Add a constant to the solution

= 12 x + \frac{x ^{2}}{2} - \frac{x ^{3}}{3} + C
