I dont know what to do

I am assuming that the whole polynomial is divided by 3.

(6x^{2} - 9x^{3} + 3)/3 Given

6x^{2}/3 - 9x^{3}/3 + 3/3 Distribute the 1/3

2x^{2} - 3x^{3} + 1 Simplify the coefficients

-3x^{3} + 2x^{2} + 1 Commutative property (change the order of terms so that the exponants are decreasing)

Writing a polynomial in standard form means that it is written with the exponants going from largest to number smallest number.
