Heya!!!

☜☆☞Here's your answer friend,

==================================

( √2 + √3 )( √2 - √3)

= [ (√2)² - (√3)² ]

........by using the identity { (a+b)(a-b) = a² - b² }

= 2 - 3 = -1

is the required answer..

==================================

Hope it helps you : )

Answer 2

hey here is your answer
=============================
formula using:
${a}^{2} - {b}^{2} = (a + b)(a - b)$
then,
$= ( \sqrt{2} + \sqrt{3} )( \sqrt{2} - \sqrt{3} ) \\ = { \sqrt{2} }^{2} - { \sqrt{3} }^{2} \\ = 2 - 3 \\ = - 1$
===========================
hope it may helpful to you
