There's no way this is an Olympiad problem.
Why?
@@francislauerBR it's easy even for a school level olimpiad question
After you move -1 to the left side, you can factor the equation by grouping.
🫶🏽
move one to the other side, use geometric series sum, the answer is clearly then the 6th roots of unity excluding 1
X=(-1)
ძალიან უკულტუროდ წერენ, აჯღაბაჯღად.

could have solve after the first factoring .
