Lösung

x^{2} - 2 x = 8

x = - 2 or x = 4

Schritte zur Lösung

x^{2} - 2 x = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x^{2} - 2 x = - 8 or x^{2} - 2 x = 8

x^{2} - 2 x = - 8 or x^{2} - 2 x = 8

3 ∣ x - 5 ∣ - 14 = - 2

3 ∣ x + 11 ∣ = 24

- 5 ∣ x - 1 ∣ + 2 = - 18

∣ 2 x - 6 ∣ = - 2

∣ 4 - 2 x ∣ = 3
