I've just found your question which has been languishing here for some time. It's actually about algebra, not geometry, so you may have better luck with such questions in the much busier news group <sci.math>.
Anyway, I'll try to answer this one now. Typing mathematical formulae is tricky, and yours hasn't got enough spaces or brackets/parentheses to make it clear. If it means
2/x - 5 - 1/x + 1 = 1
then it just amounts to 1/x = 5 which is easy to solve.
However, I suspect you may have meant
2/(x-5) - 1/(x+1) = 1
in which case multiply both sides of the equation by (x-5)(x+1) to get rid of the fractions, then switch all terms to one side and you'll have an ordinary quadratic equation.
