oyvet: (2x-y)•(c-3)

3)

Answer 2

It seems like you've provided three mathematical expressions. Let's go through each one of them:

1. xy + 2y - 2x - 4 This expression is a simple algebraic expression. If you're looking to simplify or solve for specific values, please let me know.

2. 2cx - cy - 6x + 3y This expression appears to be a linear equation involving variables c, x, and y. If you have any specific questions or if you'd like to solve it for certain values, feel free to provide more details.

3. x^2 + xy + xy^2 + y^3 This expression is a polynomial that consists of terms with different powers of x and y. If you have any particular questions or if you'd like to simplify or factorize it, please let me know.
