This is discussed in The Guide To Latex (Kopka/Daly, 3rd ed., p 130,  
sec. 5.4.1).  You need automatic sizing of brackets, and a contained  
array, as in

p\equiv\left\{\begin{array}{ll}1\pmod{4}&\Rightarrow F=\mathbb{Q} 
3\pmod{4}&\Rightarrow F=\mathbb{Q}(\sqrt{-p})\end{array}\right.

(which needs to be typeset in math mode).  I didn't find anything in  
the FAQ (not sure exactly what to search for); the automatic sizing  
of brackets is discussed there.
