The Attempt at a Solution

I don't know how to attack this one, I'm sure if I could see how to do it I could do it myself byt my head isn't working right now. All I can gather from that information is the first bit is x ^ 4 - Which isn't much. I'm thinking I have to substitue the values for zero into an equation and solve simultaneously? Can anyone help?
