@Andrei Usually questions like Why MyFun[ ] can't do ... whatever are not answerable. Mathematica inner code and algorithms are (mostly) a black box.

It's a good point that reduce can find the solution. Albeit, that does not answer the original question of why NSolve cannot. Also, Quartics->True is unnecessary.

The whole problem seems caused by foc /. {x -> 0, y -> 0} being {0,0,0}
