Lösung

x^{2} - 5 x + 8 = 2

x = 2 or x = 3

Schritte zur Lösung

x^{2} - 5 x + 8 = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x^{2} - 5 x + 8 = - 2 or x^{2} - 5 x + 8 = 2

x^{2} - 5 x + 8 = - 2 or x^{2} - 5 x + 8 = 2

keine L \overset{o}{¨} sung or (x = 2 or x = 3)

x = 2 or x = 3

∣ 8 x - 3 ∣ + 2 = 8

5 ∣ x - 4 ∣ + 9 = 20

- 8 = ∣ 4 s ∣ - 8

- 1 (a) = ∣ - 2 a + 3 ∣

3 + ∣ x ∣ = 2
