STEP 4

Factor out the common factor from the expression.
21x6=3(7x2)21x -6 =3(7x -2)

STEP 5

Check if the expression inside the parentheses can be further factorized. In this case, 7x27x -2 cannot be further factorized.
So, the completely factorized form of the expression 21x21x - is 3(7x2)3(7x -2).
