Plss mark my ans as the brainliest

Step-by-step explanation:

(2 - √2) (2 + √2)

[  (a+b) (a-b) = a² - b² ]

∴(2 - √2) (2 + √2) = (2)² - (√2)²

                             =4 - 2

                             =2

Answer 2

Answer:

(2-√2)(2+√2)

your answer is 2

2(2+√2) -√2 (2+√2)

Here we will do splitting the middle term method

4+2√2-2√2-2

so +2√2 and -2√2 will eliminate

and we get 4-2 which is 2

So your answer is 2.

Hope it will help you!
