Thanks for the challenge, which I solved in my head. However, I was only looking for real solutions - although the question did not specify that only real solutions are required.

You are welcome 😊

Yet again proving Olympiad math just means make it a million times more complicated then it needs to be.

-3²-(-3)³=9-(-27)=9+27=36
So x= -3

[@mannyalmanzar1961]

X^2-x^3 =36, x^2 -x^3= 3^2 + 3^3, x=3

[@ChidexMath2-w4h]

No, it's - 3
