Example A:

Given the following roots, write the corresponding polynomial in factored and polynomial form.  

   x =  ‑2  and ‑1

   Factors                           Polynomial Form

How do I take the zeros/roots of a polynomial and then write the equation of the polynomial?

1) Write down the zeros.

2) Write the corresponding factors of those zeros.

Example B:

Given the following roots, write the corresponding polynomial of least degree.

   x =  ‑2/3 and 1

   Factors                            Polynomial Form

Example C:

Given the following roots, write the corresponding polynomial of least degree.

   x =  3, ‑3 

   Factors                            Polynomial Form

Example D:

Given the following roots, write the corresponding polynomial of least degree.

   x =  2, 2

   Factors                            Polynomial Form
