Answer 3

It appears that you have an expression with several terms that can be simplified:

Xy + x² + y² - x² - y² + 2xy - xy

Let's simplify this step by step:

1. Combine like terms:

Xy + 2xy - xy = 2xy

x² - x² and y² - y² both cancel out because they are equal and opposite.

So, the simplified expression is:

2xy
