It goes like this:

Let X be a continuous r.v with pdf:

f(x;theta)=theta(1+theta)x^(theta-1).(1-x)

Show that the maximum likelihood estimator of theta satisifies:

a.(theta)^2+ (2+a)theta+1=0

What is 'a'? What values is f nonzero for? And be clearer with your notation please. Also, where are you having trouble?
