Given:
The zeros of the polynomial are
.
Degree = 4
Leading coefficient = 1
To find:
The polynomial.
Solution:
If c is a zero of a polynomial, then (x-c) must be a factor of the polynomial.
Here, -2,4,-5, 5, are zeros of the required polynomial, so (x+2), (x-4), (x+5), (x-5) are factors of required polynomial.

Using distributive property, we get


On combining like terms, we get


Here, the leading coefficient is 1. So, it is the required polynomial.
Therefore, the correct option is E.
