$\underline\bold{\huge{ANSWER \: :}}$
==================================

GIVEN INFORMATIONS :-

(A) a+b = 3.

(B) ab = 2.

Now, we know the formula of (a-b)².

So, on doing so, (a-b)² = a²-2ab+b²

=> (a-b)² = a²+b²-2ab

=> (a-b)² = (a+b)²-2ab-2ab

=> (a-b)² = (3)² - 4(2)

=> (a-b)² = 9-8

=> (a-b)² = 1

=> (a-b) = √1 or 1 [REQUIRED ANSWER]
