So.....I assume we have

x4 - x + 1 = 0     ???

There's not much we can do here, algebraically...let's look at the graph here.....https://www.desmos.com/calculator/u63grqdwio

Note that this function never intersects the x axis so we have no real roots or solutions !!!

(I hope this is what you have asked.....)
