z^2=-1

Lösung

z^{2} = - 1

z = i, z = - i

Schritte zur Lösung

z^{2} = - 1

Für

x^{2} = f (a)

sind die Lösungen

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

z = - 1, z = - - 1

- 1 = i

- - 1 = - i

z = i, z = - i

x^{2} = 5^{2} + 1 2^{2}

x^{2} - 289 = 0

4 (x + 7)^{2} - 49 = - 13

x^{2} - 6 x + 9 = 256

x^{2} = 7 x - 12
