I'm having some trouble getting an expression to simplify in an obvious
way. (There seems to be a long tradition of users posting to this group
with similar troubles.)

The expression is

 poly = p (p - 1) b^2 + s^2
 prod = Sqrt [poly] Sqrt[1/poly]
 Simplify[prod, {0 < p < 1, s > 0, bϵReals}]

which should return one, I think, but doesn't.

I'd be grateful for suggestions.
