I want to get the factorized format of a symbolic polynomial.
I know how to get the factors in symbolic way:
syms x
ans =
[ x - 1, x + 1]
This is an array with factors.
But, I want to get as answer something like
(x - 1)*(x + 1)
how could I get it? I remember in ancient versions this was the result.
Do I have to build this expression?
In this case, any sugestion in order to make it?
Thanks in advance.

syms x
a = factor(y)
a = 
b = a(1)*a(2)
b =

Yes, it looks like you'll have to deal with the scalar factor by hand.
