Lösung

1 - 2 x^{2} = 4

x = - \frac{5}{2} or x = \frac{5}{2}

Dezimale

x = - 1.58113 \dots, x = 1.58113 \dots

Schritte zur Lösung

1 - 2 x^{2} = 4

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

1 - 2 x^{2} = - 4 or 1 - 2 x^{2} = 4

1 - 2 x^{2} = - 4 or 1 - 2 x^{2} = 4

(x = - \frac{5}{2} or x = \frac{5}{2}) or keine L \overset{o}{¨} sung

x = - \frac{5}{2} or x = \frac{5}{2}

\frac{1}{2} ∣ x - 110 ∣ = 6

∣ x - 7 ∣ = ∣ 2 x - 2 ∣

∣ - 7 d - 8 ∣ = 71

so l v e f or y, ∣ x - 180 ∣ = 1.8 y + 90

so l v e f or x, ∣ 4 x + 5 ∣ - 4 = 20
