# Find characteristic polynomial from AR process equation [closed]

I have the following AR(2) process equation.

$$X_{t} = 1.095445 X_{t-1} - 0.3 X_{t-2} + \epsilon_{t}$$

I want to find the roots from it to ascertain whether it's a stationary process or not. How can I do this?

• Your first coefficient is so close to a very particular value that I assume this is self-study. Please add the [self-study] tag & read its wiki. Then tell us what you understand thus far, what you've tried & where you're stuck. We'll provide hints to help you get unstuck. Please make these changes as just posting your homework & hoping someone will do it for you is grounds for closing. – Stephan Kolassa Jan 12 at 11:17
