You can put this solution on YOUR website!
Be aware of minus signs! You ahve to invert the signs of the whole second poly:\r
\n" ); document.write( "\n" ); document.write( "\"%287x%5E2%2B3x-9%29-%28-x%5E2%2B8x-3%29\"
\n" ); document.write( "\"7x%5E2%2B3x-9+%2B+x%5E2+-+8x+%2B+3\"\r
\n" ); document.write( "\n" ); document.write( "Then, you sum every term that has the same literal part:\r
\n" ); document.write( "\n" ); document.write( "\"8x%5E2+-5x+-6\"
\n" ); document.write( "
\n" );
