1/((x^2+1))+1/((x-1))= 6/5

Lösung

\frac{1}{( x ^{2} + 1 )} + \frac{1}{( x - 1 )} = \frac{6}{5}

x = 2, x = - \frac{1}{12} + i \frac{71}{12}, x = - \frac{1}{12} - i \frac{71}{12}

5 (x - 1) + 5 (x^{2} + 1) = 6 (x - 1) (x^{2} + 1)

Löse

5 (x - 1) + 5 (x^{2} + 1) = 6 (x - 1) (x^{2} + 1) : x = 2, x = - \frac{1}{12} + i \frac{71}{12}, x = - \frac{1}{12} - i \frac{71}{12}

x = 2, x = - \frac{1}{12} + i \frac{71}{12}, x = - \frac{1}{12} - i \frac{71}{12}
