Problem Statement

Let α,β,γC\alpha, \beta, \gamma \in C be the roots of the polynomial x33x2+3x+7x^3 - 3x2 + 3x + 7. For any complex number zz, let f(z)f(z) be defined as follows: f(z)=zα+zβ+zγ2maxw{α,β,γ}zw.f(z) = |z -\alpha | + |z - \beta|+ |z-\gamma | - 2 \underbrace{\max}_{w \in \{\alpha, \beta, \gamma}\} |z - w|. Let AA be the area of the region bounded by the locus of all zCz \in C at which f(z)f(z) attains its global minimum. Find A\lfloor A \rfloor.
