It is Given that,
(7+ 3√5)/2 = a + b√5
=> 7/2 + (3/2)√5/= a + b√5
See, in these cases you have to compare between the two equation in order to find the value of a and b. There is no way you can solve and you will get the value.
Here we can see √5 is associated with b
and √5 is also associated with 3/2
so clearly, b = 3/2
And 7/2 is left, so a = 7/2
There is no way other than this to find an this method is called as comparison method.
Hope it helps
