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
