Answer:
(x+1)(x-3)(x-4)=0 is a polynomial equaiton with the zeros mentioned (the answers could vary-means there are multiple answers)
Explanation:
If x=-1 is a zero then (x+1) is a factor
If x=3 is a zero then (x-3) is a factor
If x=4 is a factor then (x-4) is a factor
Put it together (while the polynomial equations can be many different polynomial equations) here is one answer (x+1)(x-3)(x-4)=0
