x^2=-90

Lösung

x^{2} = - 90

x = 310 i, x = - 310 i

Schritte zur Lösung

x^{2} = - 90

Für

x^{2} = f (a)

sind die Lösungen

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

x = - 90, x = - - 90

- 90 = 310 i

- - 90 = - 310 i

x = 310 i, x = - 310 i

x^{2} + (x + 2)^{2} = 212

- 3 x^{2} = 12 x + 12

5 x^{2} + 4 x - 7 = 0

so l v e f or y, x^{2} + (y + \frac{3}{4})^{2} = 1

4 p^{2} + 23 = 7
