Factor completely:
\n" ); document.write( " $\"25a%5E2%2B64-80a\"$ Rewrite as:
\n" ); document.write( " $\"25a%5E2-80a%2B64\"$ Notice that the coefficient of $\"a%5E2\"$ is a perfect square: $\"25+=+5%5E2\"$ and the constant term is a perfect square: $\"64+=+8%5E2\"$ , so try:
\n" ); document.write( " $\"highlight%2825a%5E2-80a%2B64+=+%285a-8%29%285a-8%29%29\"$ or $\"highlight%28%285a-8%29%5E2%29\"$ \n" ); document.write( "

\n" );
