y^2=-121

Lösung

y^{2} = - 121

y = 11 i, y = - 11 i

Schritte zur Lösung

y^{2} = - 121

Für

x^{2} = f (a)

sind die Lösungen

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

y = - 121, y = - - 121

- 121 = 11 i

- - 121 = - 11 i

y = 11 i, y = - 11 i

so l v e f or r, A = π \cdot r^{2}

5 x^{2} - 43 x - 125 = 7 x

so l v e f or x, x^{2} + 3 x + 4 = 0

3 x (2 x - 6) - x (x - 5) = 9

x^{2} - 2 x - 20 = 0
