|x^2-2x-3|=0

Lösung

x^{2} - 2 x - 3 = 0

x = - 1 or x = 3

Schritte zur Lösung

x^{2} - 2 x - 3 = 0

Wende Absoluteregel an: Wenn

∣ u ∣ = 0

dann

u = 0

x^{2} - 2 x - 3 = 0

x^{2} - 2 x - 3 = 0 : x = 3, x = - 1

x = - 1 or x = 3

∣ 3 p - 5 ∣ = ∣ 2 p + 10 ∣

∣ x - 3.5 ∣ = 6.5

∣ 3 m - 4 ∣ = ∣ - 3 m + 4 ∣

∣ 3 + 7 x ∣ = 73

x \cdot ∣ x - 3 ∣ - 2 = 0
