erweitern (20x=0,)(90x-4=0,)(45x-y=0)

Lösung

erweitern

(20 x = 0,) (90 x - 4 = 0,) (45 x - y = 0)

4050 x^{2} (20 \cdot 0 =, x) - 90 x y (20 \cdot 0 =, x) = 0

Schritte zur Lösung

(20 x = 0,) (90 x - 4 = 0,) (45 x - y = 0)

= (20 \cdot 0 =, x) (90 x - 4 \cdot 0 =,) (45 x - 0 = y)

(90 x - 4 = 0,) (45 x - y = 0) : 4050 x^{2} - 90 x y = 0

= (20 x = 0,) (4050 x^{2} - 90 x y = 0)
