erweitern (-5/6 ,-3/2)y(11/2 , 1/3)

Lösung

erweitern

(- \frac{5}{6}, - \frac{3}{2}) y (\frac{11}{2}, \frac{1}{3})

- \frac{5}{6} (\frac{1}{3} \cdot \frac{11}{2},) y, - \frac{3}{2} (\frac{1}{3} \cdot \frac{11}{2},) y

Schritte zur Lösung

(- \frac{5}{6}, - \frac{3}{2}) y (\frac{11}{2}, \frac{1}{3})

= (- \frac{5}{6}, - \frac{3}{2}) (\frac{1}{3} \cdot \frac{11}{2},) y

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a = y (\frac{11}{2}, \frac{1}{3}), b = - \frac{5}{6},, c = \frac{3}{2}

= y (\frac{11}{2}, \frac{1}{3}) (- \frac{5}{6},) - y (\frac{11}{2}, \frac{1}{3}) \frac{3}{2}

+ (- a) = - a

= - \frac{5}{6} (\frac{1}{3} \cdot \frac{11}{2},) y, - \frac{3}{2} (\frac{1}{3} \cdot \frac{11}{2},) y
