x^2=-sqrt(16)

Lösung

x^{2} = - 16

x = 2 i, x = - 2 i

Schritte zur Lösung

x^{2} = - 16

16 = 4

x^{2} = - 4

Für

x^{2} = f (a)

sind die Lösungen

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

x = - 4, x = - - 4

- 4 = 2 i

- - 4 = - 2 i

x = 2 i, x = - 2 i

z^{2} + 16 z + 89 = 0

x (x - 9) = 1

(x - 5)^{2} + 7 (x - 5) = - 12

x - 4 + x (x - 3) = 4

4 x^{2} - 1 = - 6 x
