If alpha,beta,gamma are different from 1...

If `alpha,beta,gamma` are different from 1 and are the roots of `a x^3+b x^2+c x+d=0a n d(beta-gamma)(gamma-alpha)(alpha-beta)=(25)/2` , then prove that `|alpha/(1-alpha)beta/(1-beta)gamma/(1-gamma)alphabetagammaalpha^2beta^2gamma^2|=(25 d)/(2(a+b+c+d))`
