integral of (4-x)

Solution

\int (4 - x) d x

Solution

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

Solution steps

\int 4 - x 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 4 d x - \int x d x

\int 4 d x = 4 x

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

= 4 x - \frac{x ^{2}}{2}

Add a constant to the solution

= 4 x - \frac{x ^{2}}{2} + C
