Section II > Problem XVII - Pg. 46

46 A A B A A B C A BOOK ONE until now. The kind of polynomial under consideration is represented by the expression ([(u A , x ) B , (u A , y ) , (x , y ) ] , z . . . n) T This expression means the three unknowns u, x, and y satisfy the following: 1. u does not exceed the degree A, x does not exceed the degree A , y does not exceed the degree A . 2. The combination of u and x does not exceed the dimension B, u and y do not exceed the dimension B , x and y do not exceed the dimension B ; 3. The combination of u and x and y together cannot exceed a dimension larger than C. Each of the n - 3 other unknowns does not exceed a given degree; for example, z does not exceed the degree A , u does not exceed the degree A , IV x does not exceed the degree A , but the combination of two, three, four, V etc. of the variables z, u , x , etc. among themselves as well as with u, x, and y reaches all possible dimensions up to T , which is the degree of the polynomial. Problem XVII (83.) We ask for the expression of general conditions to guarantee the
