Let x^4-x^3-12x^2-3x+1 = 0 be polynomial equation. Find the list of all potential rational solutions for the polynomial equation using the rational root theorem. Then , find the actual solutions.

 

1. find all potential solution(s)

2. Find all distant actual rational solution(s)

x^4 - x^3 - 12x^2 - 3x + 1  = 0

 

1.  potential solutions  =   -1  or 1

 

2. The rational roots theorem  won't help here

 

We actually  have no  rational roots   

 

See  the (exact value) roots here calculated by WolframAlpha :

These are extremely messy......LOL!!!
