x = - 2.60555 \dots, x = 4.60555 \dots

Schritte zur Lösung

x^{2} - 2 x = 12

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x^{2} - 2 x = - 12 or x^{2} - 2 x = 12

x^{2} - 2 x = - 12 or x^{2} - 2 x = 12

keine L \overset{o}{¨} sung or (x = 1 - 13 or x = 1 + 13)

x = 1 - 13 or x = 1 + 13

∣ x + 3 ∣ = 2 x - 7

∣ x - 5 ∣ = 2 x - 1

∣ - 4 b + 8 ∣ = 4444

y + \frac{1}{4} = - 6

x^{2} - 7 ∣ x ∣ + 10 = 0
