|z+1|=1

Lösung

∣ z + 1 ∣ = 1

z = - 2 or z = 0

Schritte zur Lösung

∣ z + 1 ∣ = 1

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

z + 1 = - 1 or z + 1 = 1

z + 1 = - 1 or z + 1 = 1

z = - 2 or z = 0

∣ x + (- 3) ∣ = 25

5 ∣ 3 v - 8 ∣ = - 10

- 3 + \frac{b}{5} = - 2

- 4 = ∣ x + 2 ∣ - 5

∣ x - 4 ∣ - 5 = - 2
