If is a polynomial function of a degree  ,

then has excatly linear factors and .

Where is some non zero real number,

            are the complex zeros of .

The zero is .

Using the linear factorization therom and the zero .

The polynomial can be written as ,  where can be non zero real number.

Let .

Write the function in the standard form.

.

.

Since is a factor when .

The least degree polynomial function with integer coefficients that has as a zero is or any non multiple of .
