Could someone help me know how to factor this equation?

The rational root theorem is a helpful place to start. One factor I found very quickly was x - 1.

BTW, your thread title doesn't seem to have much to do with your question. Is this the characteristic equation for a third-order DE?
 


You're right. I was just working on the characteristic equation. But, I could figure it out. Thank you so much!
