Answer 2

It looks like you've provided a mathematical expression with various terms involving variables x and y. To simplify this expression, let's combine like terms:

2x^2 - 5xy + 2y^2 - 66x^4 - 16xy^2 - 6y^3 + 19 - 3xy + 6x^2 - 5y^2 + 816x^4y^2 + 16x^2y^4 - x^4 - y^4

Now, let's group the terms with like variables together:

(2x^2 + 6x^2 - x^4 - 66x^4 + 816x^4y^2) + (-5xy - 3xy - 16xy^2) + (2y^2 - 5y^2 - 6y^3 - y^4) + 19

Now, let's simplify each group of terms:

(2x^2 + 6x^2 - x^4 - 66x^4 + 816x^4y^2) = (8x^2 - 67x^4 + 816x^4y^2)

(-5xy - 3xy - 16xy^2) = (-8xy - 16xy^2)

(2y^2 - 5y^2 - 6y^3 - y^4) = (-4y^2 - 6y^3 - y^4)

Now, combine these simplified groups:

(8x^2 - 67x^4 + 816x^4y^2) - (8xy + 16xy^2) - (4y^2 + 6y^3 + y^4) + 19

Finally, combine like terms again:

8x^2 - 67x^4 + 816x^4y^2 - 8xy - 16xy^2 - 4y^2 - 6y^3 - y^4 + 19

So, the simplified expression is:

-67x^4 + 816x^4y^2 - 6y^3 - 16xy^2 + 8x^2 - 8xy - 4y^2 - y^4 + 19
