Answer 2

Step-by-step explanation:

Qᴜᴇsᴛɪᴏɴ ɪs ɢɪᴠᴇɴ ʙᴇʟᴏᴡ -

➦ The rationalising factor of 2( √2 + √3 ) is

Option a ➨ ( √2 + √3 )

Option b ➨ 2 ( √2 − √3 )

Option c ➨ √2 − √3

Option d ➨ 2( √2 + √3 )²

Sᴏʟᴜᴛɪᴏɴ ɪs ɢɪᴠᴇɴ ʙᴇʟᴏᴡ -

Option c ➨ √2 − √3

Fᴜʟʟ sᴏʟᴜᴛɪᴏɴ -

Option c ➨ √2 − √3 is correct because in this we have to use the identity ( rationalising factor ) –

= (a + b)(a - b) = a² - b²

Option a ➨ ( √2 + √3 ) is wrong because in this none digit ( different and opposite sides ) is cancelled.

Option b ➨ 2 ( √2 − √3 ) is not correct because there are signs of square root and one is not needed to rationalising factor.

Option d ➨ 2( √2 + √3 )² is not correct because while using identity the solution isn't come and it's cancel wrongly.
