integral of (x^3+7)

Solution

\int (x^{3} + 7) d x

Solution

\frac{x ^{4}}{4} + 7 x + C

Solution steps

\int x^{3} + 7 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^{3} d x + \int 7 d x

\int x^{3} d x = \frac{x ^{4}}{4}

\int 7 d x = 7 x

= \frac{x ^{4}}{4} + 7 x

Add a constant to the solution

= \frac{x ^{4}}{4} + 7 x + C
