x^{2} = - 100

Für

x^{2} = f (a)

sind die Lösungen

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

x = - 100, x = - - 100

- 100 = 10 i

- - 100 = - 10 i

x = 10 i, x = - 10 i

x (x - 9) = 10

so l v e f or x, x^{2} + y^{2} + 8 x - 2 y + 17 = 0

81 x^{2} - 4 = 0

- 2 x - 5 = x^{2} - 7 x - 55

(x - 3)^{2} + x^{2} = (x + 4) (x - 2) + 2
