Answer 5

Harkirat you are good

Answer 6

i try to be.......
BUT i am human too and hence make mistakes once in a while { :))


PS : As u must have realised, to solve the question, I have used
the DISTRIBUTIVE property (a-b)(c+d) = a(c+d) -b(c+d) to expand
and
the exponential laws\[\sqrt{m}*\sqrt{n}=\sqrt{m*n}\] and \[(\sqrt{m})^{2} = m\]
