∣ x - 8 ∣ = 12

x = - 4 or x = 20

Schritte zur Lösung

∣ x - 8 ∣ = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 8 = - 12 or x - 8 = 12

x - 8 = - 12 or x - 8 = 12

x = - 4 or x = 20

x^{2} - 1 = x

5 ∣ - 3.1 x + 6.9 ∣ = - 3.5

x^{2} - 3 ∣ x - 2 ∣ - 4 x = - 6

5 ∣ 2 x ∣ - 6 = 24

∣ 4 c + 2 ∣ = - 2
