y^2=15

Lösung

y^{2} = 15

y = 15, y = - 15

Dezimale

y = 3.87298 \dots, y = - 3.87298 \dots

Schritte zur Lösung

y^{2} = 15

Für

x^{2} = f (a)

sind die Lösungen

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

y = 15, y = - 15

y^{2} = 7 y

- 3 x - 12 = x - 3 x^{2}

(x - 1)^{3} - (x - 2)^{3} = 27

x^{2} + x - 420 = 0

x^{2} + 136 x = 53.76
