x^{2} = - \frac{1}{2}

Für

x^{2} = f (a)

sind die Lösungen

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

x = - \frac{1}{2}, x = - - \frac{1}{2}

- \frac{1}{2} = \frac{1}{2} i

- - \frac{1}{2} = - \frac{1}{2} i

x = \frac{1}{2} i, x = - \frac{1}{2} i

\frac{x ^{2}}{3} - \frac{1}{5} = \frac{17}{15}

x^{2} + x - \frac{11}{10} = 0

co m pl e t es q u a re 4 x^{2} - 12 x + 9 = 0

\frac{2}{3} x^{2} - 6 x = 1

(x - \frac{1}{3})^{2} = \frac{5}{9}
