∣ 3 x - 1 ∣ = 8

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

3 x - 1 = - 8 or 3 x - 1 = 8

3 x - 1 = - 8 or 3 x - 1 = 8

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

(x + 5)^{2} + 4 = 68

s im pl i f y - \frac{2}{7} - \frac{3}{4}

s im pl i f y \frac{2 - 4 i}{8 i}

0 = 3 x^{2} - 3 x

x^{2} \leq 1
