x^2+6=5|x|

Lösung

x^{2} + 6 = 5 ∣ x ∣

x = - 3 or x = - 2 or x = 2 or x = 3

Schritte zur Lösung

x^{2} + 6 = 5 ∣ x ∣

Finde positive und negative Intervalle

x < 0, x \geq 0

Löse die Ungleichung für jedes Intervall

(x = - 3 or x = - 2) or (x = 2 or x = 3)

x = - 3 or x = - 2 or x = 2 or x = 3

3 ∣ x - 3.5 ∣ + 7.5 = 7.5

∣ d - 1 ∣ = 15

3 ∣ 3 x - 4 ∣ = 24

6 = ∣ - 2 f ∣

∣ b ∣ - 4 = 11
