x^2=-30

Lösung

x^{2} = - 30

x = 30 i, x = - 30 i

Schritte zur Lösung

x^{2} = - 30

Für

x^{2} = f (a)

sind die Lösungen

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

x = - 30, x = - - 30

- 30 = 30 i

- - 30 = - 30 i

x = 30 i, x = - 30 i

a^{2} = 3

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

(x - 5)^{2} = 10

(x + a)^{2} - 3 (x + a) - 18 = 0

x^{2} + 12 x + 61 = 0
