Answer:

Step-by-step explanation:
Here we are going to apply the rule of "Square of the difference". The rule is as given below
---------(A)
Now we have our original polynomial as

Which can be re written as
---------------(B)
Hence comparing it with (A)

Applying the rule on (B)

Hence our answer is
