### William's answer to shannon's Secondary 4 A Maths Singapore question.

thank you !

hi sorry i just did the question and got a different answer from u

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

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