r^2=-13

Lösung

r^{2} = - 13

r = 13 i, r = - 13 i

Schritte zur Lösung

r^{2} = - 13

Für

x^{2} = f (a)

sind die Lösungen

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

r = - 13, r = - - 13

- 13 = 13 i

- - 13 = - 13 i

r = 13 i, r = - 13 i

\frac{4 x}{3} - x^{2} = 2 (1 - x)

s^{2} - 25 = 0

0.04 x^{2} - 2.7 x + 8.6 = 0

3 x^{2} - 16 x - 84 = 0

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