You can put this solution on YOUR website!
x/1-(1/x)=x^2/x-1, if you multiply top and bottom by x.
\n" ); document.write( "1/(1-x) + x/(x^2-1)
\n" ); document.write( "=-1(x-1 )+ x/(x+1)(x-1)
\n" ); document.write( "=-x+1+x/(x^2-1)
\n" ); document.write( "=1/(x^2-1)\r
\n" ); document.write( "\n" ); document.write( "
