erweitern (5x^2-4+7)-(3x^2=7x-1)

Lösung

erweitern

(5 x^{2} - 4 + 7) - (3 x^{2} = 7 x - 1)

2 x^{2} + 3 = 7 x + 1

Schritte zur Lösung

(5 x^{2} - 4 + 7) - (3 x^{2} = 7 x - 1)

= (5 x^{2} - 4 + 7) - (3 \cdot 7 = x^{2} x - 1)

- (3 x^{2} = 7 x - 1) : - 3 x^{2} = 7 x + 1

(5 x^{2} - 4 + 7) - 3 x^{2} = 7 x + 1
