Answer : The denominator of the simplified expression is, (3n-2)
Step-by-step explanation :
The given expression is:

Now we are multiplying numerator.


Now we are taking common 'n' in numerator.

Now we are cancelling the term (6n+4), we get:

In this expression:
Numerator = n
Denominator = (3n-2)
Therefore, the denominator of the simplified expression is, (3n-2)
