If `alpha and beta` are roots of equation `x^2 + 4x + p = 0` where `p = sum_(r=0)^n nC_r (1+rx)/(1+nx)^r(-1)^r`,then the value of `|alpha-beta|` is

Let alpha and beta the roots of equation px^(2) + qx + =0 p ne 0 if p,q,r are in A.P and (1)/(alpha) + (1)/(beta) =4 then the value of |alpha -beta| is :
