Good Evening!

To the Experts,
I am the asker of this question. 

Actually, I tried to prove my actual question. Firstly, I took the L.C.M to be 4c2 and then put the law of exponents and then finally applied, a2 - b2 = (a+b)(a-b).

Using this I got my answer. 

So, I would recommend not to answer this now un-necessarily. 

Thanking You, 

Good Night!
