|x^2-6x-4|=0

Lösung

x^{2} - 6 x - 4 = 0

x = 3 - 13 or x = 3 + 13

Dezimale

x = - 0.60555 \dots, x = 6.60555 \dots

Schritte zur Lösung

x^{2} - 6 x - 4 = 0

Wende Absoluteregel an: Wenn

∣ u ∣ = 0

dann

u = 0

x^{2} - 6 x - 4 = 0

x^{2} - 6 x - 4 = 0 : x = 3 + 13, x = 3 - 13

x = 3 - 13 or x = 3 + 13

\frac{b}{4} = 8

∣ 0.127 x + 9 ∣ = x^{2}

11 = ∣ 3 x + 5 ∣

4 ∣ 3 (x + 3) (x - 3) ∣ - 4 = 4

3 ∣ y + 5 ∣ + 7 = 10
