p u n t os (2, - 1) y (\frac{1 , - 9}{7})

2 (\frac{1 , - 9}{7}) p n u t osy, - 1 \cdot (\frac{1 , - 9}{7}) p n u t osy

Schritte zur Lösung

p u n t os (2, - 1) y (\frac{1 , - 9}{7})

= (\frac{1 , - 9}{7}) (2, - 1) p n u t osy

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a = p u n t osy (\frac{1 , - 9}{7}), b = 2,, c = 1

= p u n t osy (\frac{1 , - 9}{7}) \cdot 2, - p u n t osy (\frac{1 , - 9}{7}) \cdot 1

= 2 (\frac{1 , - 9}{7}) p n u t osy, - 1 \cdot (\frac{1 , - 9}{7}) p n u t osy
