Lösung

erweitern

A (2, \frac{3}{4}) B (\frac{3}{5}, - \frac{1}{2})

\frac{3}{5} (2 \cdot \frac{3}{4},) A B, - \frac{1}{2} (2 \cdot \frac{3}{4},) A B

Schritte zur Lösung

A (2, \frac{3}{4}) B (\frac{3}{5}, - \frac{1}{2})

= (2 \cdot \frac{3}{4},) (\frac{3}{5}, - \frac{1}{2}) A B

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a = A (2, \frac{3}{4}) B, b = \frac{3}{5},, c = \frac{1}{2}

= A (2, \frac{3}{4}) B \frac{3}{5}, - A (2, \frac{3}{4}) B \frac{1}{2}

= \frac{3}{5} (2 \cdot \frac{3}{4},) A B, - \frac{1}{2} (2 \cdot \frac{3}{4},) A B
