|4x-1|=4

Lösung

∣ 4 x - 1 ∣ = 4

x = - \frac{3}{4} or x = \frac{5}{4}

Dezimale

x = - 0.75, x = 1.25

Schritte zur Lösung

∣ 4 x - 1 ∣ = 4

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

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

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

x = - \frac{3}{4} or x = \frac{5}{4}

- \frac{4}{9} d^{2} + \frac{8}{3} d = 0

(x - 2)^{2} = 21

3 x - 5 = 16

f a c t or 4 x^{2} - 16 x + 12

- 6 < 4 - 2 x \leq 8
