Lösung

y^{2} = 125

y = 55, y = - 55

Dezimale

y = 11.18033 \dots, y = - 11.18033 \dots

Schritte zur Lösung

y^{2} = 125

Für

x^{2} = f (a)

sind die Lösungen

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

y = 125, y = - 125

125 = 55

- 125 = - 55

y = 55, y = - 55

x^{2} + 8 x + 40 = 0

2 x^{2} - 15 x + 20 = 0

5 x^{2} = 135

2 a^{2} + a - 3 = 0

(x + 9)^{2} + 8 (x + 9) + 12 = 0
