We demonstrate that, under suitable local conditions on a finite collection F 1 ,…, F g of binary irreducible forms with integer coefficients, the product F 1 ( x )·…· F g ( x ) will have at most r prime factors for infinitely many x . We give explicit upper bounds for r that depend only on g and on the total degree of the product polynomial.
