integral of 9x-3

Solution

\int 9 x - 3 d x

Solution

\frac{9 x ^{2}}{2} - 3 x + C

Solution steps

\int 9 x - 3 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 9 x d x - \int 3 d x

\int 9 x d x = \frac{9 x ^{2}}{2}

\int 3 d x = 3 x

= \frac{9 x ^{2}}{2} - 3 x

Add a constant to the solution

= \frac{9 x ^{2}}{2} - 3 x + C
