Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

or

u = - a

5 u^{4} - 7 = - 5 or 5 u^{4} - 7 = 5

5 u^{4} - 7 = - 5 or 5 u^{4} - 7 = 5

(u = - 4 \frac{2}{5} or u = 4 \frac{2}{5}) or (u = - 4 \frac{12}{5} or u = 4 \frac{12}{5})

u = - 4 \frac{12}{5} or u = - 4 \frac{2}{5} or u = 4 \frac{2}{5} or u = 4 \frac{12}{5}
