b = 5, b = - 5

Dezimale

b = 2.23606 \dots, b = - 2.23606 \dots

Schritte zur Lösung

b^{2} = 5

Für

x^{2} = f (a)

sind die Lösungen

x = f (a), - f (a)

b = 5, b = - 5

(x + 2)^{2} - 3 (x + 2) - 4 = 0

1250000 + 60000 x - 6000 x^{2} = 0

x^{2} - 40 x + 240 = 0

x^{2} - 4 x + 3 = 2 x^{2} + 2 x + 3

2 w^{2} - 5 w = 3
