Jun 15, 2022 at 14:41	comment	added	Gro-Tsen		To put it differently, you are asking for a condition on complex numbers $(z_{i,j})_{1≤i≤3,1≤j≤3}$ (sufficiently general) such that all three of $h_1,h_2,h_3$ where $h_i = ((t-z_{i,2})(z_{i,3}-z_{i,1})) / ((t-z_{i,1})(z_{i,3}-z_{i,2}))$ are simultaneously real for some $t\in\mathbb{C}$.
