|x^2-x-4|=2

Lösung

x^{2} - x - 4 = 2

x = - 2 or x = - 1 or x = 2 or x = 3

Schritte zur Lösung

x^{2} - x - 4 = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x^{2} - x - 4 = - 2 or x^{2} - x - 4 = 2

x^{2} - x - 4 = - 2 or x^{2} - x - 4 = 2

(x = - 1 or x = 2) or (x = - 2 or x = 3)

x = - 2 or x = - 1 or x = 2 or x = 3

5 ∣ 3 x - 4 ∣ = x + 1

∣ 4 x - 7 ∣ + 7 = 3 x

∣ 6 x - 3 ∣ = 15

∣ 3 x - 1 ∣ + 8 + x = x + 4

60 = ∣ 10 y ∣
