|2(x-1)|=5

Lösung

∣ 2 (x - 1) ∣ = 5

x = - \frac{3}{2} or x = \frac{7}{2}

Dezimale

x = - 1.5, x = 3.5

Schritte zur Lösung

∣ 2 (x - 1) ∣ = 5

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

2 (x - 1) = - 5 or 2 (x - 1) = 5

2 (x - 1) = - 5 or 2 (x - 1) = 5

x = - \frac{3}{2} or x = \frac{7}{2}

5 x + 9 = 54

0 = 3 x^{2} - 6 x

820 = x (1.05)^{3}

3 (x - 4) \geq 5 x + 2

f a c t or 10 x^{2} + 6 x - 4
