Löse

9 y^{2} - 12 y + 7 = 0 : y = \frac{2}{3} + i \frac{3}{3}, y = \frac{2}{3} - i \frac{3}{3}

y = \frac{2}{3} + i \frac{3}{3}, y = \frac{2}{3} - i \frac{3}{3}

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

\frac{4}{x} = \frac{5}{2 x} + 3

- \frac{7}{4 x} + \frac{5}{6 x} = 1

5 = \frac{5}{a x} + 1

\frac{2 x ^{2} - 5 x + 3}{10 x - 5} = 0
