|x|=13

Lösung

∣ x ∣ = 13

x = - 13 or x = 13

Schritte zur Lösung

∣ x ∣ = 13

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x = - 13 or x = 13

x^{2} - 16 x + 64 \leq 0

4 x^{2} + 11 x - 20 = 0

0.5 - ∣ x - 12 ∣ = - 0.25

2 x^{2} + 3 x - 7 = x^{2} + 5 x + 39

(x + 3)^{2} = - 49
