Step-by-step explain

this is a formula based question

formula; (a+b)(a-b)= a raise to 2 -b raise to 2

so u write

(root 3) raise to 2 -(root 7) raise to 2

then,

if u multiply roots u will get only the number the roots will go

so,

= 3-7   , now subract it

because 7 is having the minus and it is a big number ,

so we write the big numbers sign
