(x - \frac{1}{2}) (x - \frac{1}{2}) : x^{2} - x + \frac{1}{4}

= \int_{0}^{1} x^{2} - x + \frac{1}{4} d x

Wende die Summenregel an:

\int f (x) \pm g (x) d x = \int f (x) d x \pm \int g (x) d x

= \int_{0}^{1} x^{2} d x - \int_{0}^{1} x d x + \int_{0}^{1} \frac{1}{4} d x

\int_{0}^{1} x^{2} d x = \frac{1}{3}

\int_{0}^{1} x d x = \frac{1}{2}

\int_{0}^{1} \frac{1}{4} d x = \frac{1}{4}

= \frac{1}{3} - \frac{1}{2} + \frac{1}{4}

Vereinfache

\frac{1}{3} - \frac{1}{2} + \frac{1}{4} : \frac{1}{12}

= \frac{1}{12}
