Given equation:
To find:
- Value of a and b
Solution:
By rationalising the LHS of given equation, (i.e. by multiplying both numerator and denominator of LHS with the rationalising factor which is 3 + √7), we get:
Now, use the following identities:
On comparing LHS and RHS, we get:

Answer :-
- Hence, option (c) is correct.
Step by step explanation :-
Given expression :
First we rationalize the denominator,
Using (a+b)² identity in numerator and (a+b) (a-b) identity use in denominator,
Comparing LHS and RHS we get,
- a = 8
- b = 3
Hence, option (c) is correct.
