ln(x+1)=ln(3x+1) - lnx
\n" ); document.write( "ln(x+1)=ln{(3x+1)/x}...taking antilogs
\n" ); document.write( "x+1=(3x+1)/x
\n" ); document.write( "x(x+1)=3x+1
\n" ); document.write( "x^2+x-3x-1=0
\n" ); document.write( "x^2-2x-1=0..using 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( "\"x+=+%282+%2B-+sqrt%28+%28-2%29%5E2-4%2A1%2A%28-1%29+%29%29%2F%282%2A1%29+\"
\n" ); document.write( "x=1+sqrt.(2)....or......1-sqrt.(2)..but since logof negative number does not exist...1-sqrt.(2) cannot be a solution.
\n" ); document.write( "so...x=1+sqrt.2=2.4142
\n" ); document.write( "
\n" );
