Answer:
(3/2, 0+), (-1, 0+)
Step-by-step explanation:
An exact "zero" of a polynomial is characterized by a point on the x-axis. In this case the best approximation to that is the point (3/2, 0+); the next best approximation is (-1, 0+). Note that neither of these two points actually lies on the x-axis, but that both are closer to the x-axis than are any of the other given points.
