What is the factorization of the polynomial graphed below? Assume it has no constant factor. Write each factor as a polynomial in descending order.

Answer:
(x+4)(x-4)
Step-by-step explanation:
If a graph intersect the x- axis at a point x=a, then the polynomial can be factored as (x-a).
Because the graph crosses the x- axis at x=-4 and x=4, then the two factors are (x+4) and (x-4).
