complex number ?? 1. The problem statement, all variables and given/known data Let ω be the solution to the equation x2+x+1=0 Get the value of ω10+ω5+3= 2. Relevant equations complex numbers??? 3. The attempt at a solution When I try solving the first equation I hit a complex number which is making me think I am wrong. (x+1/2)2=-3/4 Again if the method is right, what is the relationship between the complex number and the later expression?
