Let w=zzˉ+k1z+k2izˉ+λ(1+i)w = z\bar{z} + k_1 z + k_2 i\bar{z} + \lambda(1 + i), k1,k2Rk_1, k_2 \in \mathbb{R}. If the curve Re(w)=0\text{Re}(w) = 0 is the circle CC of radius 11 in the first quadrant touching the line y=1y = 1 and the yy-axis, and the curve Im(w)=0\text{Im}(w) = 0 intersects CC at AA and BB, then 30(AB)230(AB)^2 is equal to:
