= [\frac{1}{4} x (x + 5)^{2} - \int \frac{1}{2} x (x + 5) d x]_{0}^{1}

\int \frac{1}{2} x (x + 5) d x = \frac{1}{2} (\frac{x ^{3}}{3} + \frac{5 x ^{2}}{2})

= [\frac{1}{4} x (x + 5)^{2} - \frac{1}{2} (\frac{x ^{3}}{3} + \frac{5 x ^{2}}{2})]_{0}^{1}

Vereinfache

[\frac{1}{4} x (x + 5)^{2} - \frac{1}{2} (\frac{x ^{3}}{3} + \frac{5 x ^{2}}{2})]_{0}^{1} : [\frac{1}{12} (x^{3} + 15 x^{2} + 75 x)]_{0}^{1}

= [\frac{1}{12} (x^{3} + 15 x^{2} + 75 x)]_{0}^{1}
