integral of x-9

Solution

\int x - 9 d x

Solution

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

Solution steps

\int 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 d x - \int 9 d x

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

\int 9 d x = 9 x

= \frac{x ^{2}}{2} - 9 x

Add a constant to the solution

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