Schritte zur Lösung

3 x^{2} - 15 = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x^{2} - 15 = - 3 or 3 x^{2} - 15 = 3

3 x^{2} - 15 = - 3 or 3 x^{2} - 15 = 3

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

x = - 6 or x = - 2 or x = 2 or x = 6

3 = ∣ v + 2 ∣

∣ 4 - x ∣ + 2 x = 3

9 - 6 ∣ 665 - 7 w ∣ = - 831

- ln ∣ 120 - x ∣ = k t

∣ x - 3 ∣ = - 2 x
