integral of-x^2+7

Solution

\int - x^{2} + 7 d x

Solution

- \frac{x ^{3}}{3} + 7 x + C

Solution steps

\int - x^{2} + 7 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 x^{2} d x + \int 7 d x

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

\int 7 d x = 7 x

= - \frac{x ^{3}}{3} + 7 x

Add a constant to the solution

= - \frac{x ^{3}}{3} + 7 x + C
