Expert Solution
Step 1 EXPLANATION

The given expression is

                                    21x-14xy

Now we factorize the given expression

                                 21x-14xy

                              =(3·7·x-2·7·x·y)

                              =7(3·x-2·x·y)     ( factor out the common term 7 )

                              =7·x(3-2·y)         ( factor out the common term x )

                              =7x(3-2y)

                              =7×x×(3-2y)

  My friend make mistake in the term (3-2xy) because in the correct factorization it will be (3-2y)
