Answer:

⇒  [Factorized form]
        [Factorized form]
Step-by-step explanation:
Given expression:

We need to make  the subject.
 the subject.
In order to do that we need to solve the expression for  in terms of
 in terms of  and
 and 
We have,

Subtracting both sides by 


Taking square root both sides in order to remove square of 


The difference of squares can be factorized and written  as:
 [difference of squares
    [difference of squares  ]
 ]
