2/(1+x^2)=x

Lösung

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

x = 1, x = - \frac{1}{2} + i \frac{7}{2}, x = - \frac{1}{2} - i \frac{7}{2}

2 = x (1 + x^{2})

Löse

2 = x (1 + x^{2}) : x = 1, x = - \frac{1}{2} + i \frac{7}{2}, x = - \frac{1}{2} - i \frac{7}{2}

x = 1, x = - \frac{1}{2} + i \frac{7}{2}, x = - \frac{1}{2} - i \frac{7}{2}

\frac{4}{x} - 8 = - 2

\frac{4}{5 x} = 11

0 = \frac{x + 1}{x + 2}

\frac{2}{t} = \frac{t}{5 t - 12}
