∣ x - 10 ∣ = 8

x = 2 or x = 18

Schritte zur Lösung

∣ x - 10 ∣ = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 10 = - 8 or x - 10 = 8

x - 10 = - 8 or x - 10 = 8

x = 2 or x = 18

(4 x + 7) (x - 1) = (2 x + 1)^{2}

- 6 k + 1 = - 2 + 7 k

2 x^{2} = 6 x - 1

2 x + 50 = 6 x + 2
