x^{2} = - 2

Für

x^{2} = f (a)

sind die Lösungen

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

x = - 2, x = - - 2

- 2 = 2 i

- - 2 = - 2 i

x = 2 i, x = - 2 i

(x - 21)^{2} = 25

y^{2} - 121 = 0

so l v e f or x, 5 x^{2} - 4 x y + 5 y^{2} - 21 = 0

so l v e f or x, 3 x^{2} - 16 x + 16 = 0

46 = - 16 (t)^{2} + 50 (t) + 10
