Schritte zur Lösung

(\frac{5}{2})^{2} - 5 (\frac{5}{2}) + 6

Apply rule:

(a) = a

(\frac{5}{2}) = \frac{5}{2}

= (\frac{5}{2})^{2} - 5 \cdot \frac{5}{2} + 6

(\frac{5}{2})^{2} = \frac{25}{4}

5 \cdot \frac{5}{2} = \frac{25}{2}

= \frac{25}{4} - \frac{25}{2} + 6

\frac{25}{4} - \frac{25}{2} + 6 = - \frac{1}{4}

= - \frac{1}{4}
