solve for x;
\n" ); document.write( "lnx+ln(x+1)=1
\n" ); document.write( "ln(x)(x+1)=1
\n" ); document.write( "e=x^2+x
\n" ); document.write( "x^2+x-e=0
\n" ); document.write( "solve for x by quadratic formula:
\n" ); document.write( "\"x+=+%28-b+%2B-+sqrt%28+b%5E2-4%2Aa%2Ac+%29%29%2F%282%2Aa%29+\"
\n" ); document.write( "a=1, b=1, c=-e
\n" ); document.write( "x=[-1±√(1-4*1*-e)]/2
\n" ); document.write( "x=[-1±√(1+4e)]/2
\n" ); document.write( " \n" ); document.write( "
\n" );
