integral of 2x^7+4x^6+x^5+1

\int 2 x^{7} + 4 x^{6} + x^{5} + 1 d x

\frac{x ^{8}}{4} + \frac{4 x ^{7}}{7} + \frac{x ^{6}}{6} + x + C

Solution steps

\int 2 x^{7} + 4 x^{6} + x^{5} + 1 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 2 x^{7} d x + \int 4 x^{6} d x + \int x^{5} d x + \int 1 d x

\int 2 x^{7} d x = \frac{x ^{8}}{4}

\int 4 x^{6} d x = \frac{4 x ^{7}}{7}

\int x^{5} d x = \frac{x ^{6}}{6}

\int 1 d x = x

= \frac{x ^{8}}{4} + \frac{4 x ^{7}}{7} + \frac{x ^{6}}{6} + x

Add a constant to the solution

= \frac{x ^{8}}{4} + \frac{4 x ^{7}}{7} + \frac{x ^{6}}{6} + x + C
