2.1.2. Очень часто приведение многочлена к стандартному виду можно осуществить путём применения формул сокращённого умножения. One way is to notice that if a,b,c,d are four integers such that the product of any two of them is a "shy square", i.e., ab = x^2 - 1 ac = y^2 - 1 ad = z^2 - 1 bc = u^2 - 1 bd = v^2 - 1 cd = w^2 - 1 (1) then clearly (abcd) can be expressed in at least three ways, namely abcd = (ab)(cd) = (ac)(bd) = (ad)(bc) (2) There are some nice parametric formulas for sets of four numbers with property (1).
