Which of the following are terms in the sum of the given polynomials? 3x2,-2x2y, 2xy2, 4y2, xy2, - y2,2x2y

3

3x2

3y2

3xy2

4x22

Create the sum of the given polynomial terms.

f (x, y) = 3x² - 2x²y + 2xy² + 4y² + xy² - y² + 2x²y

= 3x² + 3xy² + 3y²

Test the given terms to see if they belong in f (x, y).

3: NO

3x²: YES

3y²: YES

3xy²: YES

4x²: NO

Answer:

The terms in the sum of the given polynomials are 3x², 3y², and 3xy².
