The complex number z satisfies z^2 + z + 1 = 0. Find z2+z
z^2 + z = ((-1+-isqrt(3)))^2/4 + (-1+-isqrt(3))/2 Then just add them up by multiplying the right one by 2/2
Just move the 1 to the right-hand side and it's done.
z2+z+1=0(z2+z+1)−1=0−1z2+z=−1
Lol I'm the dumbest human of all time
No, please don't say that. Sometimes we miss the most obvious things. I think you will not miss it next time, so that is progress!
