4

x^{2} = - \frac{15}{4}

Für

x^{2} = f (a)

sind die Lösungen

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

x = - \frac{15}{4}, x = - - \frac{15}{4}

- \frac{15}{4} = \frac{15}{2} i

- - \frac{15}{4} = - \frac{15}{2} i

x = \frac{15}{2} i, x = - \frac{15}{2} i

x^{2} + (x - 4)^{2} = 20

a x^{2} + 2 x + c = 2

3 x^{2} - 14 x = x^{2} + 12

- 5 + 16 x^{2} = 95

(4 x - 1)^{2} = 16
