∣ x - 7 ∣ = 24

x = - 17 or x = 31

Schritte zur Lösung

∣ x - 7 ∣ = 24

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 7 = - 24 or x - 7 = 24

x - 7 = - 24 or x - 7 = 24

x = - 17 or x = 31

5 x + 8 = 18

f a c t or 70 x^{2} - 90 x + 20

∣ 2 x - 3 ∣ \geq 0.4

f a c t or 30 x^{2} + 9 x - 12

6 x^{2} - 18 x = 0
