can I take any number for comman

Answer 1

Answer:

You can take any number as common but here in this step you have to only 2 because there is no other option other than 2.and another thing while taking 2x as a common factor your answer will be 2x(1-18). Because 2x*1 you get 2x . if you multiply 2x * x - 18, you will get 2x*x as 2x^2 i.e. 2x square and then - 36x
