A highway underpass has a parabolic shape. A parabola is the graph that results from p(x) = ax² + bx + c. Parabolas are symmetric about a vertical line known as the Axis of Symmetry.
The Axis of Symmetry runs through the maximum or minimum point of the parabola, known as the vertex.


Based on the given information, answer the following questions:
(ii) The highway overpass is represented graphically. Zeros of a polynomial can be expressed graphically.
Number of zeros of polynomial is equal to which points
(2)
Highway Underpass whose one zero is 6 and sum of the zeros is 0, then write the polynomial.
