|sqrt(x)-6|=3

Lösung

x - 6 = 3

x = 9 or x = 81

Schritte zur Lösung

x - 6 = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 6 = - 3 or x - 6 = 3

x - 6 = - 3 or x - 6 = 3

x = 9 or x = 81

roo t s ∣ a - x ∣

∣ 3 x - 12 ∣ = 8

1 - ∣ x - 1 ∣ = 0

- 2 - 6 ∣ - 9 x + 7 ∣ = 10

∣ 3 x + 8 ∣ = 29
