counterexample:
int x^2 =(X^3)/3
int x * int x = (x^4)/4
i tried to solve it earlier but didnt manage to get to an answer i used to be good at those, but it's been a long time since i had to integrate a difficult expression
Oh yeah, it has to be + or - between them... was too long scince I did this.
