Schritte zur Lösung

x^{4} - 2 x^{2} - 2 = 0

Wende Absoluteregel an: Wenn

∣ u ∣ = 0

dann

u = 0

x^{4} - 2 x^{2} - 2 = 0

x^{4} - 2 x^{2} - 2 = 0 : x = 1 + 3, x = - 1 + 3

x = - 1 + 3 or x = 1 + 3

∣ q + 4 ∣ = 4

∣ 4 n - 2 ∣ = 2

2 - 3 x = - 10 + 3 ∣ 2 - 2 x ∣

∣ 2 x - 10 ∣ = 10

(x + 1) = ∣ x - 5 ∣
