माना की `alpha, beta` समीकरण `px^2 + qx + r = 0, p ne 0` के मूल है | यदि `p, q, r` समान्तर श्रेणी में हों तथा `1/alpha+ 1/beta=4` तो | `alpha - beta` | का मात्र है :

Let alpha and beta be the roots of equation px^(2) + qx + r = 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 :
