integral of (x+4)

Solution

\int (x + 4) d x

Solution

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

Solution steps

\int x + 4 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 4 d x

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

\int 4 d x = 4 x

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

Add a constant to the solution

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