Lösung

∣ 8 x + 32 ∣ = 40

x = - 9 or x = 1

Schritte zur Lösung

∣ 8 x + 32 ∣ = 40

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

8 x + 32 = - 40 or 8 x + 32 = 40

8 x + 32 = - 40 or 8 x + 32 = 40

x = - 9 or x = 1

x^{2} = ∣ x - 1 ∣

∣ 9 x + 1 ∣ = 1

∣ 2 x + (- 1) ∣ = 5

∣ - 10 + n ∣ - 2 = - 8

4 x^{2} + 8 x + 3 = 1
