Lösung

x^{2} - 6 x = 7

x = - 1 or x = 3 - 2 or x = 3 + 2 or x = 7

Dezimale

x = - 1, x = 1.58578 \dots, x = 4.41421 \dots, x = 7

Schritte zur Lösung

x^{2} - 6 x = 7

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x^{2} - 6 x = - 7 or x^{2} - 6 x = 7

x^{2} - 6 x = - 7 or x^{2} - 6 x = 7

(x = 3 - 2 or x = 3 + 2) or (x = - 1 or x = 7)

x = - 1 or x = 3 - 2 or x = 3 + 2 or x = 7

∣ w - 2 ∣ = 0

\frac{∣ x ∣}{7} = 5

x^{2} - 5 x + 6 = ∣ x - 3 ∣

∣ 2 x ∣ = 1

∣ e - 3 ∣ = 24
