a^2=-4

Lösung

a^{2} = - 4

a = 2 i, a = - 2 i

Schritte zur Lösung

a^{2} = - 4

Für

x^{2} = f (a)

sind die Lösungen

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

a = - 4, a = - - 4

- 4 = 2 i

- - 4 = - 2 i

a = 2 i, a = - 2 i

5 x^{2} + 12 x + 2 = 0

0 = 6 x^{2} + 6 x - 36

co m pl e t es q u a re x^{2} + 4 x - 1 = 0

x^{2} - 14 x - 120 = 0

x^{2} - 6 x + 2 = - 3
