\r
\n" ); document.write( "\n" ); document.write( "\"4ab-20a%2B15c-3bc\" Start with the given expression\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"4ab-20a-3bc%2B15c\" Rearrange the terms.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%284ab-20a%29%2B%28-3bc%2B15c%29\" Group like terms\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"4a%28b-5%29-3c%28b-5%29\" Factor out the GCF \"4a\" out of the first group. Factor out the GCF \"-3c\" out of the second group\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%284a-3c%29%28b-5%29\" Since we have the common term \"b-5\", we can combine like terms\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So \"4ab-20a-3bc%2B15c\" factors to \"%284a-3c%29%28b-5%29\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "In other words, \"4ab-20a-3bc%2B15c=%284a-3c%29%28b-5%29\"
\n" ); document.write( "
\n" ); document.write( "
\n" );
