|x-8|=8

Lösung

∣ x - 8 ∣ = 8

x = 0 or x = 16

Schritte zur Lösung

∣ x - 8 ∣ = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

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

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

x = 0 or x = 16

x^{2} - 4 x + 7 = 2 x^{2} - 3 x + 5

∣ 10 x + 9 ∣ = 18

x^{2} - 4 x = - 5

∣ x + 1 ∣ + ∣ x - 2 ∣ + ∣ x - 5 ∣ = x + 4

x^{2} - 2 = 2 - 3 x
