\n" ); document.write( "y^2 = 5x^2 + 25
\n" ); document.write( "y^2 - 5x^2 = 25
\n" ); document.write( "y^2/25 - x^2/5 = 1
\n" ); document.write( "a = 5
\n" ); document.write( "b = \"sqrt%285%29\"
\n" ); document.write( "\"a%5E2+%2B+b%5E2+=+c%5E2\"
\n" ); document.write( "\"25+%2B+5+=+c%5E2\"
\n" ); document.write( "\"30+=+c%5E2\"
\n" ); document.write( "\"sqrt%2830%29+=+c\"
\n" ); document.write( "(0,\"sqrt%2830%29\") and (0,-\"sqrt%2830%29\")
\n" ); document.write( "
\n" );
