erweitern x(x+1)-(4-x)(x+1=6(4-x))

Lösung

erweitern

x (x + 1) - (4 - x) (x + 1 = 6 (4 - x))

x^{2} - 3 x - 4 = 24 + 6 x

Schritte zur Lösung

x (x + 1) - (4 - x) (x + 1 = 6 (4 - x))

= x (x + 1) - (4 - x) (x + 1 \cdot 6 = (4 - x))

x (x + 1) : x^{2} + x

= x^{2} + x - (4 - x) (x + 1 = 6 (4 - x))

- (4 - x) (x + 1 = 6 (4 - x)) : - 4 x - 4 = 24 + 6 x

x^{2} + x - 4 x - 4 = 24 + 6 x
