integral of (x^4+x+9)

\int (x^{4} + x + 9) d x

\frac{x ^{5}}{5} + \frac{x ^{2}}{2} + 9 x + C

Solution steps

\int x^{4} + x + 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 x^{4} d x + \int x d x + \int 9 d x

\int x^{4} d x = \frac{x ^{5}}{5}

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

\int 9 d x = 9 x

= \frac{x ^{5}}{5} + \frac{x ^{2}}{2} + 9 x

Add a constant to the solution

= \frac{x ^{5}}{5} + \frac{x ^{2}}{2} + 9 x + C
