Please answer the 11th question​

Answer 1

since p(1) = p(2) =p(3) = 0 => 1,2 and 3 are roots of this polynomial there we got a polynomial with roots 1,2 and 3 and we divide it by the given polynomial and then the remainder should come zero thus we made reminder = 0 and we got values of a,b,c and d.
