y^2=-49

Lösung

y^{2} = - 49

y = 7 i, y = - 7 i

Schritte zur Lösung

y^{2} = - 49

Für

x^{2} = f (a)

sind die Lösungen

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

y = - 49, y = - - 49

- 49 = 7 i

- - 49 = - 7 i

y = 7 i, y = - 7 i

so l v e f or x, x^{2} + y^{2} - 10 x + 2 y + 26 = 0

2 x^{2} - 5 x + 15 = 0

5 x^{2} = - 45

x^{2} + 5 x + c = 0

5 p - 15 p^{2} = 0
