Factor:\r
\n" ); document.write( "\n" ); document.write( " $\"%282a%2B4%29%28a-3%29-%282a%2B4%29%282a-1%29\"$ Notice the common factor in the two terms? Factor it out>\r
\n" ); document.write( "\n" ); document.write( " $\"%282a%2B4%29%28%28a-3%29-%282a-1%29%29\"$ Now simplify.\r
\n" ); document.write( "\n" ); document.write( " $\"2%28a%2B2%29%28-a-2%29\"$ Rewrite (-a-2) as -(a+2) and move the negative sign to the front.\r
\n" ); document.write( "\n" ); document.write( " $\"-2%28a%2B2%29%28a%2B2%29\"$ \n" ); document.write( "
