Let u = {x | X be less than or equal to 5, and X belong to n *}, a = {x | x ^ 2-5x + q = 0}, B = {x | x ^ 2 + PX + 12 = 0}, and (CUA) UB = {1,2,3,4,5} Finding p q Is the question wrong? It's impossible,

A simple analysis shows that a and B have solutions, the sum of the two solutions in a is equal to 5, the product of the two solutions in B is 12, and the solutions are positive integers. Then there are two cases: 1. The two solutions in a are 1,4 respectively, while the two solutions in B can only be 3,4, which is not in line with the meaning of the problem
