Finding the minimal polynomial of an irrational over Q

[QUOTE="PsychonautQQ, post: 5605640, member: 482086"] [h2]Homework Statement [/h2] Let a = (1+(3)^1/2)^1/2. Find the minimal polynomial of a over Q. [h2]Homework Equations[/h2][h2]The Attempt at a Solution[/h2] Maybe the first thing to realize is that Q(a):Q is probably going to be 4, in order to get rid of both of the square roots in the expression. I also suspect that +/-(3)^1/2 will be roots of the minimal polynomial, as Q(a):Q = [Q(a):Q((3)^1/2)]*[Q(3^1/2):Q]. I do not know where to go from here, any advice PF? [/QUOTE]
