|2x+4|=2

Lösung

∣ 2 x + 4 ∣ = 2

x = - 3 or x = - 1

Schritte zur Lösung

∣ 2 x + 4 ∣ = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 x + 4 = - 2 or 2 x + 4 = 2

2 x + 4 = - 2 or 2 x + 4 = 2

x = - 3 or x = - 1

(x - 3) (x + 1)^{2} (x - 8) \geq 0

9 + x < 9

4 (x - 2) - 5 x \geq - 3

13.5 x + 20 = 17 x + 6

5 (- 7 + 9) \leq 10
