Hi everyone, 1. The problem statement, all variables and given/known data P(X)=Xp-1*(X-1)p*...*(X-n)p j is an integer between 1 and n; x a real beatween 0 and 1. Prove that abs(P(jx))<=(n!)p 2. Relevant equations 3. The attempt at a solution I tried to find an inequality for each abs(jx-q) but the problem is that I can't control j*x... Any clue is welcome!
