Question: How to find set of coordinates in Maple?

Hello, forgive me if I used bad english, I am not a native speaker.


Anyhow: I have to decide the set of coordinates looking at the grafs intersections.  (I hope you understand that)


This is my function: f(x)=1/4*x3-x2-x+4


When you plot the function you see that the intersections is (-2,0) (2,0) and (4,0)


BUT I have to use a command to find these three intersections, plzz help me!


THANK YOU indeed.
