Lösung

erweitern

(\frac{1}{2}, \frac{7}{2}) y (- \frac{8}{5}, - \frac{6}{5})

- \frac{8}{5} (\frac{1}{2} \cdot \frac{7}{2},) y, - \frac{6}{5} (\frac{1}{2} \cdot \frac{7}{2},) y

Schritte zur Lösung

(\frac{1}{2}, \frac{7}{2}) y (- \frac{8}{5}, - \frac{6}{5})

= (\frac{1}{2} \cdot \frac{7}{2},) (- \frac{8}{5}, - \frac{6}{5}) y

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a = (\frac{1}{2}, \frac{7}{2}) y, b = - \frac{8}{5},, c = \frac{6}{5}

= (\frac{1}{2}, \frac{7}{2}) y (- \frac{8}{5},) - (\frac{1}{2}, \frac{7}{2}) y \frac{6}{5}
