(5x)/(x^2+9)=-1

Lösung

\frac{5 x}{x ^{2} + 9} = - 1

x = - \frac{5}{2} - i \frac{11}{2}, x = - \frac{5}{2} + i \frac{11}{2}

5 x = - (x^{2} + 9)

Löse

5 x = - (x^{2} + 9) : x = - \frac{5}{2} - i \frac{11}{2}, x = - \frac{5}{2} + i \frac{11}{2}

x = - \frac{5}{2} - i \frac{11}{2}, x = - \frac{5}{2} + i \frac{11}{2}

\frac{25}{f + 2} = \frac{5}{3}

\frac{7}{x + 4} = 4 + \frac{5}{x - 2}

\frac{x}{x - 2} + 5 = \frac{2}{x - 2}

so l v e f or t, P = \frac{W}{t}

\frac{y - 1}{y + 1} = \frac{3}{y + 3}
