z^2=-25

Lösung

z^{2} = - 25

z = 5 i, z = - 5 i

Schritte zur Lösung

z^{2} = - 25

Für

x^{2} = f (a)

sind die Lösungen

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

z = - 25, z = - - 25

- 25 = 5 i

- - 25 = - 5 i

z = 5 i, z = - 5 i

16 x^{2} + 16 x + 1 = 0

0 = 2 x^{2} - 9 x + 4

4 x^{2} - 4 x + 10 = 0

3 - 4 x + x^{2} = 0

4 x^{2} - 17 x = - 4
