\n" ); document.write( "\n" ); document.write( "Why I said \"probably\", highlighted by red ?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Because the problem can be treated in different way, as if one dimension is 1 unit,
\n" ); document.write( "while the other dimension is the trinomial x^2 + 11x + 18.\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Then the answer is, SURELY, totally different.\r
