|k^2-5k|=6

Lösung

k^{2} - 5 k = 6

k = - 1 or k = 2 or k = 3 or k = 6

Schritte zur Lösung

k^{2} - 5 k = 6

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

k^{2} - 5 k = - 6 or k^{2} - 5 k = 6

k^{2} - 5 k = - 6 or k^{2} - 5 k = 6

(k = 2 or k = 3) or (k = - 1 or k = 6)

k = - 1 or k = 2 or k = 3 or k = 6

∣ v + 3 ∣ = 5

x^{2} + 7 x - 8 = ∣ x + 1 ∣

ln ∣ y (C) ∣ + C = 3

∣ q - 50 ∣ + 1 = 21
