Factor:
\n" ); document.write( " $\"40a%5E8%2B16a%5E7%2B25a%5E9\"$ First, factor $\"a%5E7\"$
\n" ); document.write( " $\"a%5E7%2840a%2B16%2B25a%5E2%29\"$ Rearrange the trinomial in order of descending powers of a.
\n" ); document.write( " $\"a%5E7%2825a%5E2%2B40a%2B16%29\"$ Now factor the trinomial in parentheses.
\n" ); document.write( " $\"a%5E7%285a%2B4%29%285a%2B4%29\"$ or $\"a%5E7%285a%2B4%29%5E2\"$ \n" ); document.write( "

\n" );
