Detailed Solution

Given-

(3 + 2) (3 − 2)

.
To determine the value of

(3 + 2) (3 − 2)

after simplifying it.
We can simplify it as,

3 + 2 3 − 2 = 32 − 22 ⇒ 3 + 2 3 − 2 = 3 − 2 [∵ a 2 − b 2 = (a + b) (a − b)] ⇒ 3 + 2 3 − 2 = 1

Thus, the value of

(3 + 2) (3 − 2)

after simplifying it is 1.
Hence, option 2 is the correct option.
