|16-x^2|=20

Lösung

16 - x^{2} = 20

x = - 6 or x = 6

Schritte zur Lösung

16 - x^{2} = 20

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

16 - x^{2} = - 20 or 16 - x^{2} = 20

16 - x^{2} = - 20 or 16 - x^{2} = 20

(x = - 6 or x = 6) or keine L \overset{o}{¨} sung

x = - 6 or x = 6

∣ x - 3 ∣ + ∣ x - 4 ∣ = 3

∣ x + 3 ∣ + ∣ x ∣ = 7

so l v e f or f, ∣ f ∣ = 2

∣ x - 1 ∣ + ∣ x + 1 ∣ = 2

∣ 5 y + 2 ∣ = 0
