Lösung

∣ - 2 x ∣ = 10

x = - 5 or x = 5

Schritte zur Lösung

∣ - 2 x ∣ = 10

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

- 2 x = - 10 or - 2 x = 10

- 2 x = - 10 or - 2 x = 10

x = - 5 or x = 5

4 x^{3} - 36 x^{2} + 8 x + 192 > 0

s im pl i f y \frac{a}{b} + \frac{b}{a}

3 x^{2} - 18 x + 12 = 0

2 (2 x - 9) \leq 6

(- 5 x - 1) (2 x + 8) = 0
