|x^2+6x-8|=8

Lösung

x^{2} + 6 x - 8 = 8

x = - 8 or x = - 6 or x = 0 or x = 2

Schritte zur Lösung

x^{2} + 6 x - 8 = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x^{2} + 6 x - 8 = - 8 or x^{2} + 6 x - 8 = 8

x^{2} + 6 x - 8 = - 8 or x^{2} + 6 x - 8 = 8

(x = - 6 or x = 0) or (x = - 8 or x = 2)

x = - 8 or x = - 6 or x = 0 or x = 2

x^{2} - 13 = 3

- 2 ∣ x + 8 ∣ = 20

∣ 3 x - 5 ∣ = 2 - x

5 ∣ x - 4 ∣ - 9 = 2

∣ 3 x + 5 ∣ + 8 = 7
