Apr 12 at 20:55	comment	added	user526214		In my question I assume that the conic $Q(x,y)$ defined in $\mathbb{R}^2$ is real and irreducible. Now, what if the zeros of $P(x,y)$ and $Q(x,y)$ coincide in $\mathbb{R}^2$ but not in $\mathbb{C}^2$ as stated to apply Hilbert's Nullstellensatz? So is there a counterexample to my question?
