[QUOTE="nuuskur, post: 6049692, member: 519618"] You can optimise [tex] \frac{1}{z} + \frac{1}{2-z} = 1 \iff \frac{1}{z} = 1 + \frac{1}{z-2} \iff \frac{1}{z} = \frac{z-1}{z-2} \iff z^2 -2z +2 =0. [/tex] and you get solutions ##1\pm i ##. If you have something of the form ##\frac{a}{f(x)} + \frac{b}{g(x)} = c ##, perhaps it's not such a hot idea to immediately mess with the common denominators and such. [/QUOTE]
