What are symmetric expression & how is it used for factorisation of polynomials?
Asked by araima2001 | 13th May, 2014, 11:06: AM
Symmetric expression is an expression, if it is invariant under any permutations of its variables,
That is, if you change the position of the variables, the value of the expression is unaltered.
Consider the expression
Here, different permutations are: :
Thus, the values are:
It is clear that the values are invariant.
Now to check the factorization of
Hence the factorization of
