4

x^{2} = - \frac{9}{4}

Für

x^{2} = f (a)

sind die Lösungen

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

x = - \frac{9}{4}, x = - - \frac{9}{4}

- \frac{9}{4} = \frac{3}{2} i

- - \frac{9}{4} = - \frac{3}{2} i

x = \frac{3}{2} i, x = - \frac{3}{2} i

x^{2} + 14 x + 18 = 0

(x + 5) (x + 4) = 0

2 (3 x + 5)^{2} - 2 = 70

5 x^{2} - 15 x + 1 = 0

21 x^{2} - 16 x - 50 = 0
