|x^2+3x-15|=3

Lösung

x^{2} + 3 x - 15 = 3

Lösung

x = - 6 or x = \frac{- 3 - 57}{2} or x = \frac{- 3 + 57}{2} or x = 3

+1

Dezimale

x = - 6, x = - 5.27491 \dots, x = 2.27491 \dots, x = 3

Schritte zur Lösung

x^{2} + 3 x - 15 = 3

Wende Absoluteregel an: Wenn

∣ u ∣ = a, a > 0

dann

u = a

or

u = - a

x^{2} + 3 x - 15 = - 3 or x^{2} + 3 x - 15 = 3

x^{2} + 3 x - 15 = - 3 or x^{2} + 3 x - 15 = 3

(x = \frac{- 3 - 57}{2} or x = \frac{- 3 + 57}{2}) or (x = - 6 or x = 3)

x = - 6 or x = \frac{- 3 - 57}{2} or x = \frac{- 3 + 57}{2} or x = 3
