Let $\"z=a-b\"$ \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So the expression $\"%28a-b%29%5E5%2B4%28a-b%29%5E3\"$ becomes $\"z%5E5%2B4z%5E3\"$ \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"z%5E5%2B4z%5E3\"$ Start with the given expression\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"z%5E3%28z%5E2%2B4%29\"$ Factor out the GCF $\"z%5E3\"$ \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"%28a-b%29%5E3%28%28a-b%29%5E2%2B4%29\"$ Plug in $\"z=a-b\"$ \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"%28a-b%29%5E3%28a%5E2-2ab%2Bb%5E2%2B4%29\"$ FOIL\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So $\"%28a-b%29%5E5%2B4%28a-b%29%5E3\"$ factors to $\"%28a-b%29%5E3%2A%28a%5E2-2a%2Ab%2Bb%5E2%2B4%29\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In other words, $\"%28a-b%29%5E5%2B4%28a-b%29%5E3=%28a-b%29%5E3%2A%28a%5E2-2a%2Ab%2Bb%5E2%2B4%29\"$
