Answer:

Step-by-step explanation:
Given:


Required:
LCM of the polynomials
SOLUTION:
Step 1: Factorise each polynomial








Step 2: find the product of each factor that is common in both polynomials.
We have the following,

The common factors would be: =>
(this is common in both polynomials, so we would take just one of them as a factor.
and,

Their product = 
The answer for this question is 4.
DE. AB, is going up BC, isn't decreasing or increasing. CD, isn't decreasing or increasing. Therefore your answer is DE.
