\n" ); document.write( "\n" ); document.write( "\"2p-6q%2Bpq-3q%5E2\" Start with the given expression\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%282p-6q%29%2B%28pq-3q%5E2%29\" Group like terms\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"2%28p-3q%29%2Bq%28p-3q%29\" Factor out the GCF of \"2\" out of the first group. Factor out the GCF of \"q\" out of the second group\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%282%2Bq%29%28p-3q%29\" Since we have a common term of \"p-3q\", we can combine like terms\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So \"2p-6q%2Bpq-3q%5E2\" factors to \"%282%2Bq%29%28p-3q%29\"\r
