integral of x^7-3x+2

Solution

\int x^{7} - 3 x + 2 d x

Solution

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

Solution steps

\int x^{7} - 3 x + 2 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^{7} d x - \int 3 x d x + \int 2 d x

\int x^{7} d x = \frac{x ^{8}}{8}

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

\int 2 d x = 2 x

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

Add a constant to the solution

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