If is a polynomial function of degree , then has excatly linear factors and

.

Where is some non zero real numbe,

           are the complex zeros of .

The zeros are .

Using the linear factorization therom and the zeros , we can write as follows.

.

While can be any non zero real number, it is simplest to let .

Then write the function in the standard form.

.

.

Therefore, a function of least degree that has as zeros is

or any non multiple of .
