u^2=-13

Lösung

u^{2} = - 13

u = 13 i, u = - 13 i

Schritte zur Lösung

u^{2} = - 13

Für

x^{2} = f (a)

sind die Lösungen

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

u = - 13, u = - - 13

- 13 = 13 i

- - 13 = - 13 i

u = 13 i, u = - 13 i

q u a d r a t i c f or m u l a - t^{2} + 6 t - 9 = 0

120 w^{2} + 1800 w - 4080 = 0

so l v e f or t, - 0.8 t^{2} + 32 t = 0
