ln (x+8)+ln (x-8)=0
\n" ); document.write( "ln (x+8)+ln (x-8) = ln(1)
\n" ); document.write( "ln ((x+8)(x-8)) = ln(1)
\n" ); document.write( "(x+8)(x-8) = 1
\n" ); document.write( "\"x%5E2+-+64+=+1\"
\n" ); document.write( "\"x%5E2+=+65\"
\n" ); document.write( "x =~ 8.062258
\n" ); document.write( "------------
\n" ); document.write( "x =~ -8.062258 won't work, no logs of negative numbers
