If Alina wrote the last term as 3y3, which must be the first term of her polynomial in standard form

-8x^2y

Step-by-step explanation:

First collect like terms of xy^2 and 4xy^2(since their variables and deggres are the same) and you get: 5xy^2 - 2x^2y + 3y^3 - 6x^2y

Then collect like terms of -2x^2y and -6x^2(since their variables and deggres are the same) and you get: 5xy^2 - 8x^2y + 3y^2

The problem states "which must be the first term of her polynominal in standard form?"

That means that the polynominal Alina is talking about is -8x^2y.      

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
