|x-1|=2

Lösung

∣ x - 1 ∣ = 2

x = - 1 or x = 3

Schritte zur Lösung

∣ x - 1 ∣ = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 1 = - 2 or x - 1 = 2

x - 1 = - 2 or x - 1 = 2

x = - 1 or x = 3

x^{2} - 10 x - 12 = 0

4 x^{2} + 9 x + 7 = 0

s im pl i f y \frac{54 x ^{5} y ^{3}}{2 x ^{2} y}

\frac{1}{2} a = 11

x^{4} - 3 x^{2} - 10 > 0
