= x (8 x + 8 x^{3} + \frac{24 x ^{5}}{5} + \frac{8 x ^{7}}{7}) - \int 8 x + 8 x^{3} + \frac{24 x ^{5}}{5} + \frac{8 x ^{7}}{7} d x

\int 8 x + 8 x^{3} + \frac{24 x ^{5}}{5} + \frac{8 x ^{7}}{7} d x = 4 x^{2} + 2 x^{4} + \frac{4 x ^{6}}{5} + \frac{x ^{8}}{7}

= x (8 x + 8 x^{3} + \frac{24 x ^{5}}{5} + \frac{8 x ^{7}}{7}) - (4 x^{2} + 2 x^{4} + \frac{4 x ^{6}}{5} + \frac{x ^{8}}{7})

Vereinfache

x (8 x + 8 x^{3} + \frac{24 x ^{5}}{5} + \frac{8 x ^{7}}{7}) - (4 x^{2} + 2 x^{4} + \frac{4 x ^{6}}{5} + \frac{x ^{8}}{7}) : \frac{8 x ^{8}}{7} - \frac{x ^{8}}{7} + \frac{24 x ^{6}}{5} - \frac{4 x ^{6}}{5} + 6 x^{4} + 4 x^{2}
