Help with geometry problems.

[courtney]

Help needed for geometry problems, looking for descriptions on how these problems were solved and answers.

Solve this equation by using the quadratic form.
2/x-5-1/x+1=1

( more questions will be added later )

hey,

im a junior in switzerland and i use the services of a mathematician. whenever i cant solve a problem, or too much homework or a take home test i scan and send the problems to him he sends them back real fast. he charges though. would you be interested?

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.

2/x-5-1/x+1=1

plz.. first clarify..

is it 2/(x-5)-1/(x+1)=1

or (2/x)-5-(1/x)+1=1

for the second type.. there is no need to go into quadratic equations
