Hey friend, Here is your answer-
a+b root 7 = 3 / ( root 7 + 2)
a+b root 7 =3 ×( root 7 - 2)/
(root 7 +2) × ( root 7 - 2).......... ( by rationalisation)
a+b root 7 = 3 root 7 - 6 / 7 - 4
a + b root 7= 3 root 7 - 6 / 3
a+b root 7= root 7-2
a+b root 7= -2 + root 7
Therefore, a = -2 and b=1
Hope it will help you.

9004:
/ symbol is there in the question
check it
I think it had mistake. because if we solve it in that way , we can't get value of a and b
I got it. I am editing my answer
ok
I think now you will get a=-6/3
b=3/3
Yes it is right
yes now it's right
Hmm
