z^2=-9

Lösung

z^{2} = - 9

z = 3 i, z = - 3 i

Schritte zur Lösung

z^{2} = - 9

Für

x^{2} = f (a)

sind die Lösungen

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

z = - 9, z = - - 9

- 9 = 3 i

- - 9 = - 3 i

z = 3 i, z = - 3 i

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

x^{2} + (\frac{5}{6})^{2} = 1

s^{2} - 49 = 0

so l v e f or x, 4 x^{2} + 9 (m x - 1)^{2} = 5

2 5^{2} = 7^{2} + b^{2}
