You can put this solution on YOUR website!
3cd – 6cy + 2xd – 4xy
\n" ); document.write( "Start by grouping the terms (that have similar factors):
\n" ); document.write( "[3cd – 6cy] + [2xd – 4xy]
\n" ); document.write( "factoring terms inside the brackets:
\n" ); document.write( "3c[d – 2y] + 2x[d – 2y]
\n" ); document.write( "finally, pulling out the (d-2y):
\n" ); document.write( "(d-2y)(3c+2x)
\n" ); document.write( ".
\n" ); document.write( "Your choice would be: 3
\n" ); document.write( "
\n" );
