Homework Help: Probably a rather easy Algebra problem that I am not getting

  1. Jan 30, 2005 #1
    If [tex]\sqrt{9+4\sqrt{5}}=\sqrt{a}+\sqrt{b}[/tex], find all ordered pairs (a,b)

    The equation looks hauntingly like a elliptic curve, so I tried that but it didnt really help. I tried just simplifing it, but it got really messy really fast. Can someone please help?
