x = - 15 or x = 3

Schritte zur Lösung

∣ x + 6 ∣ = 9

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x + 6 = - 9 or x + 6 = 9

x + 6 = - 9 or x + 6 = 9

x = - 15 or x = 3

f a c t or 3 x^{2} - 4 x y - 4 y^{2}

(7 x - 2)^{2} = 4

∣ x - 2 ∣ \geq 5

- 4 m \geq - 4

2 x^{2} - 4 x - 70 = 0
