y^2=99

Lösung

y^{2} = 99

y = 311, y = - 311

Dezimale

y = 9.94987 \dots, y = - 9.94987 \dots

Schritte zur Lösung

y^{2} = 99

Für

x^{2} = f (a)

sind die Lösungen

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

y = 99, y = - 99

99 = 311

- 99 = - 311

y = 311, y = - 311

- 20 + 7 x + 3 x^{2} = 0

x^{2} + 2 x + 2 = 2

x^{2} - 44 = 100

t^{2} + t + 2 = 0

so l v e f or x, x^{2} + 2 x y + y^{2} = 25
