integral of (5x^2+9)

Solution

\int (5 x^{2} + 9) d x

Solution

\frac{5 x ^{3}}{3} + 9 x + C

Solution steps

\int 5 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 5 x^{2} d x + \int 9 d x

\int 5 x^{2} d x = \frac{5 x ^{3}}{3}

\int 9 d x = 9 x

= \frac{5 x ^{3}}{3} + 9 x

Add a constant to the solution

= \frac{5 x ^{3}}{3} + 9 x + C
