i got c= 1 instead of c=1/3
and my equation is
y=9x^3 - 9x^2 + 3x +1
i did the check like what u did and mine matched i think there was a tiny mistake with yours ? i’m not sure though

This depends on where you put the “c” during the integration. The tutor placed it inside the bracketed term. For me, I usually placed it outside.

Regardless of the position, your final answer at the end should be the same.
