integral of-x+3

Solution

\int - x + 3 d x

Solution

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

Solution steps

\int - 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 x d x + \int 3 d x

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

\int 3 d x = 3 x

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

Add a constant to the solution

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