Homework Statement
Find roots of the EQN: r^3-r^2+1=0
Homework Equations
none
The Attempt at a Solution
r^2(r-1)+1=0
from there i solved, r^2=-1 and r-1=-1 to find the following roots:
r=+i,r=-i, r=0
Is my method correct? Also, I don't think that synthetic division would work here since my possible rational zeroes are +1/-1, and those don't satisfy the equation when they are plugged in for 'r'.
