      Why is it there are not five roots since this is is a fifth degree polynomial? Check the roots by generating a graph of this equation using your calculator. With other polynomial functions, we will not be able to draw upon our knowledge of factoring quadratic functions. For example, you may not be able to factor , but could still find its zeros by graphing it in your calculator. What are the ...
