Here is the original problem.
\n" ); document.write( " $\"81b%5E6-3d%5E6\"$
\n" ); document.write( "we can rewrite this as
\n" ); document.write( " $\"3%5E4b%5E6-3d%5E6\"$
\n" ); document.write( "we see a GCF of 3, so taking that out, we get
\n" ); document.write( " $\"3%283%5E3b%5E6+-+d%5E6%29\"$
\n" ); document.write( "in the parentheses we can rewrite as
\n" ); document.write( " $\"3%28%283b%5E2%29%5E3+-+%28d%5E2%29%5E3%29\"$
\n" ); document.write( "this is a difference of cubes and we get
\n" ); document.write( " $\"3%28%283b%5E2-d%5E2%29%2A%289b%5E4+%2B+3%28bd%29%5E2+%2B+d%5E4%29%29\"$ \n" ); document.write( "
