Fleming · Answer 1

To write a polynomial in its standard form, arrange the exponents of the variables in decreasing order giving the priority to the first variable that appears in the alphabetical order. So, from the given above, the answer would be

2x³y + 7y²x - 3x² - 12y

Thus, the answer is letter A.
