(1/9 h^6 + 6/7 h^2) + (3/4 h^6-1/28h^2)
\n" ); document.write( "(1/9 + 3/4)h^6 +(6/7 -1/28)h^2
\n" ); document.write( "Use 36 as a common denominator for the h^6 coefficient
\n" ); document.write( "(4/36 + 27/36)h^6 + (6/7 -1/28)h^2
\n" ); document.write( "No use 28 as the common denominator for the h^2 coefficient
\n" ); document.write( "(4/36 + 27/36)h^6 + (24/28 -1/28)h^2
\n" ); document.write( " $\"%2831%2F36%29h%5E6+%2B+%2823%2F28%29h%5E2\"$
\n" ); document.write( "One could factor out h^2 to get
\n" ); document.write( " $\"h%5E2%28+%2831%2F36%29h%5E6+%2B+%2823%2F28%29+%29\"$
