Solution:

Given that,

A polynomial, p(x), has a lead coefficient of 1 and exactly three distinct zeros

The zeros are:

x = -1 is a zero of multiplicity two

x = 2 is a zero of multiplicity one

x = 4 is a zero of multiplicity one

Zero of multiplicity means "How many times a particular number is a zero for a given polynomial"

Therefore,

x = -1

x + 1 = 0 , with multiplicity of two

x = 2

x - 2 = 0, with multiplicity one

x = 4

x - 4 = 0, with multiplicity one

The polynomial p(x) is given as:

p(x) is equal to product of zeros

p(x) = (x+1)^2(x-2)(x-4)p(x)=(x+1)
