integral of 3x+8

Solution

\int 3 x + 8 d x

Solution

\frac{3 x ^{2}}{2} + 8 x + C

Solution steps

\int 3 x + 8 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 3 x d x + \int 8 d x

\int 3 x d x = \frac{3 x ^{2}}{2}

\int 8 d x = 8 x

= \frac{3 x ^{2}}{2} + 8 x

Add a constant to the solution

= \frac{3 x ^{2}}{2} + 8 x + C
