|x-3|=(-2+sqrt(34))/2

Lösung

∣ x - 3 ∣ = \frac{- 2 + 34}{2}

x = - \frac{- 2 + 34}{2} + 3 or x = \frac{- 2 + 34}{2} + 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

u = - a

x - 3 = - \frac{- 2 + 34}{2} or x - 3 = \frac{- 2 + 34}{2}

x - 3 = - \frac{- 2 + 34}{2} or x - 3 = \frac{- 2 + 34}{2}

x = - \frac{- 2 + 34}{2} + 3 or x = \frac{- 2 + 34}{2} + 3

x^{2} + 12 x - 20 = 0

(n - 8) (n + 3) = 0

3 (5) - 2 (0) = - 5

3 y - 5 < - 8 or 2 y - 1 > 5

3 y^{2} - 15 y = 0
