Dear student
Please ask only one question in one thread.
(iv)
this can be proved using factor theorem
if a is replqced by b then it becomes 0
hence (a – b) is a factor similarly (b – c) and ( c – a) is a factor.
hence it is assumed as k ( a – b) (b – c) (c – a) ( ab + bc + ca)
Now compare any term
we gett k = 1
hencce
= ( a – b) (b – c) (c – a) ( ab + bc + ca)
