Lösung

∣ 5 - 2 x ∣ = 13

x = - 4 or x = 9

Schritte zur Lösung

∣ 5 - 2 x ∣ = 13

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

5 - 2 x = - 13 or 5 - 2 x = 13

5 - 2 x = - 13 or 5 - 2 x = 13

x = - 4 or x = 9

∣ x + 19 ∣ = ∣ x - 12 ∣

6 ∣ 4 x + 4 ∣ = 24

f a c t or 3 x^{3} + 4 x^{2} + 6 x + 8

7^{2} + x^{2} = 1 1^{2}
