Let one of the number be \"+x+\"
\n" ); document.write( "\"+f%28x%29+=+x%2A%28+28+-++x+%29\"
\n" ); document.write( "\"+f%28x%29+=+-x%5E2+%2B+28x+\"
\n" ); document.write( "\"+x%5Bmax%5D+=+-28%2F%282%2A%28-1%29%29+\"
\n" ); document.write( "\"+x%5Bmax%5D+=+14+\"
\n" ); document.write( "and
\n" ); document.write( "\"+28+-+x+=+14+\"
\n" ); document.write( "Both numbers are 14
