Investigation on the Roots of Polynomials. Let’s review by finding the roots of quadratic functions. Look at the graph of . Use completing the square or the quadratic formula to verify the solutions you found on the graph. Now, we will try to find roots of polynomials of larger degrees. Let’s start with the cubic polynomial .

The characteristic polynomial is defined as: The roots of = 0 will give the necessary information about the stationarity or nonstationarity of the process. The necessary and sufficient condition for stability is that all characteristic roots lie outside the unit circle. Then is of full rank and all variables are stationary.
