Lösung

erweitern

P_{1} (6, 1) P_{2} (1, - 4)

1 \cdot (6 \cdot 1,) P_{1} P_{2}, - 4 (6 \cdot 1,) P_{1} P_{2}

Schritte zur Lösung

P_{1} (6, 1) P_{2} (1, - 4)

= (6 \cdot 1,) (1, - 4) P_{1} P_{2}

Wende das Distributivgesetz an:

a (b - c) = ab - a c

a = P_{1} (6, 1) P_{2}, b = 1,, c = 4

= P_{1} (6, 1) P_{2} \cdot 1, - P_{1} (6, 1) P_{2} \cdot 4

= 1 \cdot (6 \cdot 1,) P_{1} P_{2}, - 4 (6 \cdot 1,) P_{1} P_{2}
