Are you sure that the equation isn't \"3y-21%2Bxy-7x\" ??\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3y-21%2Bxy-7x\" Start with the given expression\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%283y-21%29%2B%28xy-7x%29\" Group like terms\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3%28y-7%29%2Bx%28y-7%29\" Factor out the GCF \"3\" out of the first group. Factor out the GCF \"x\" out of the second group\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"%283%2Bx%29%28y-7%29\" Since we have the common term \"y-7\", we can combine like terms\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So \"3y-21%2Bxy-7x\" factors to \"%283%2Bx%29%28y-7%29\"
\n" ); document.write( "
\n" );
