\r
\n" ); document.write( "\n" ); document.write( " $\"8x%5E3%2B4x%5E2-2x-1\"$ Start with the given expression\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"%288x%5E3%2B4x%5E2%29%2B%28-2x-1%29\"$ Group like terms\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"4x%5E2%282x%2B1%29-1%282x%2B1%29\"$ Factor out the GCF $\"4x%5E2\"$ out of the first group. Factor out the GCF $\"-1\"$ out of the second group\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"%284x%5E2-1%29%282x%2B1%29\"$ Since we have the common term $\"2x%2B1\"$ , we can combine like terms\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So $\"8x%5E3%2B4x%5E2-2x-1\"$ factors to $\"%284x%5E2-1%29%282x%2B1%29\"$
\n" ); document.write( " \n" ); document.write( "

\n" );
