9xy and -4xy
When multiplying a polynomial, we needed to multiply all of them one-by-one. to get the product.
(2x + 3y) (3x - 2y)
We can use FOIL Method.
F: (2x)(3x) = 6x²
O: (2x)(-2y) = -4xy
I: (3y)(3x) = 9xy
L: (3y)(-2y) = -6y²
Then, we need to arrange them according to their degrees.
6x² - 4xy + 9xy - 6y²
6x² - 6y² + 9xy - 4xy
6x² - 6y² + 5xy
Then, the final answer is 6x² - 6y² + 5xy. But the ones that we need to combine are the terms 9xy and -4xy.
Why? Because they are like terms because they are the same in degree and their variables.

Answer:
9xy and -4xy
Explanation:
When multiplying a polynomial, we needed to multiply all of them one-by-one. to get the product.
(2x + 3y) (3x - 2y)
We can use FOIL Method.
F: (2x)(3x) = 6x²
O: (2x)(-2y) = -4xy
I: (3y)(3x) = 9xy
L: (3y)(-2y) = -6y²
Then, we need to arrange them according to their degrees.
6x² - 4xy + 9xy - 6y²
6x² - 6y² + 9xy - 4xy
Combine 9xy and -4xy
6x² - 6y² + 5xy
Then, the final answer is 6x² - 6y² + 5xy. But the ones that we need to combine are the terms 9xy and -4xy.
Why? Because they are like terms because they are the same in degree and their variables.
