integral of-10x^2+9

Solution

\int - 10 x^{2} + 9 d x

Solution

- \frac{10 x ^{3}}{3} + 9 x + C

Solution steps

\int - 10 x^{2} + 9 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 10 x^{2} d x + \int 9 d x

\int 10 x^{2} d x = \frac{10 x ^{3}}{3}

\int 9 d x = 9 x

= - \frac{10 x ^{3}}{3} + 9 x

Add a constant to the solution

= - \frac{10 x ^{3}}{3} + 9 x + C
