\"%289x%5E2+-8x+%2B+1%29%288x+-+1%29\"\r

\n" ); document.write( "\n" ); document.write( "\"%288x+-+1%29%289x%5E2+-8x+%2B+1%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"8x%289x%5E2+-8x+%2B+1%29+-+1%289x%5E2+-8x+%2B+1%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"8x%289x%5E2%29%2B8x%28+-8x%29%2B8x%281%29+-+1%289x%5E2%29-1%28+-8x%29-1%281%29\"\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So \"%289x%5E2+-8x+%2B+1%29%288x+-+1%29\" expands out to \"72x%5E3-73x%5E2%2B16x-1\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In other words \"%289x%5E2+-8x+%2B+1%29%288x+-+1%29=72x%5E3-73x%5E2%2B16x-1\"\r
