|x^2+x-2|=0

Lösung

x^{2} + x - 2 = 0

x = - 2 or x = 1

Schritte zur Lösung

x^{2} + x - 2 = 0

Wende Absoluteregel an: Wenn

∣ u ∣ = 0

dann

u = 0

x^{2} + x - 2 = 0

x^{2} + x - 2 = 0 : x = 1, x = - 2

x = - 2 or x = 1

∣ x + 9 ∣ + 7 = 6

∣ 13 y + 9 ∣ + 8 = 2

∣ 2 x - 7 ∣ + 1 = 9

∣ 2 x - 10 ∣ - 7 = - 5

∣ 6 - 5 x ∣ = 2
