Quick Context: Alternate Approach Consider simpler versions of the problem, perhaps just N = a1 3 + a0 N = {+1, 0, -1} 3 + {+1, 0, -1} produces ... We can focus on a ≥ 0 because a ≤ 0 gives an upward parabola intersecting the top of the circle at a single real point.

Alternate Approach Consider simpler versions of the problem, perhaps just N = a1 3 + a0 N = {+1, 0, -1} 3 + {+1, 0, -1} produces ... We can focus on a ≥ 0 because a ≤ 0 gives an upward parabola intersecting the top of the circle at a single real point. Selected region is also easy because both x and y are positive so x = x and y = y.
