|t^2-99|=1

Lösung

t^{2} - 99 = 1

t = - 10 or t = - 72 or t = 72 or t = 10

Dezimale

t = - 10, t = - 9.89949 \dots, t = 9.89949 \dots, t = 10

Schritte zur Lösung

t^{2} - 99 = 1

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

t^{2} - 99 = - 1 or t^{2} - 99 = 1

t^{2} - 99 = - 1 or t^{2} - 99 = 1

(t = - 72 or t = 72) or (t = - 10 or t = 10)

t = - 10 or t = - 72 or t = 72 or t = 10

- 4 ∣ 4 - 8 b ∣ = 12

- 3 ∣ x + 2 ∣ + 6 = 15

9 = ∣ 2 x - 5 ∣

∣ U - 2 ∣ = - \frac{1}{2}

2 ∣ 3 x - 4 ∣ + 1 = 3
