Lösung

∣ 4 x - 1 ∣ = 2

x = - \frac{1}{4} or x = \frac{3}{4}

Dezimale

x = - 0.25, x = 0.75

Schritte zur Lösung

∣ 4 x - 1 ∣ = 2

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

4 x - 1 = - 2 or 4 x - 1 = 2

4 x - 1 = - 2 or 4 x - 1 = 2

x = - \frac{1}{4} or x = \frac{3}{4}

2 + 1 - \frac{x}{2} \geq 5

∣ m + 7 ∣ = 12

- 3 x^{2} = 150

f a c t or x^{3} - 8 x^{2} + x + 42

∣ x - 3 ∣ = ∣ 3 x + 5 ∣
