Answer 2

Answer:

1

Step-by-step explanation:

For the given equation to be an identity in ‘x’, the equation must be satisfied for all x.

One way is: Putting x = 0, and x = 1, we can narrow down the value as a = 2

OR : (a-2) is a common factor of the terms, so if a = 2, the equation becomes an identity in x.
