Answer 2

To simplify the expression 4 - 2xy + 5x^2 - 3y^2, there's nothing to solve or set to a specific value since it's just a mathematical expression. However, we can try to simplify it by combining like terms:

The given expression is: 4 - 2xy + 5x^2 - 3y^2

To simplify, we can rearrange it in descending order of powers: 5x^2 - 2xy - 3y^2 + 4

And that's the simplified form of the expression.
