It seems like you're working with an algebraic expression. Let's first rewrite and simplify the expression you've provided:

\[ 5(2 - x)^2 + xy - 2y \]

Assuming you're looking to simplify or manipulate this expression, here's how to do it step by step:

1. **Expand \( (2 - x)^2 \)**:
\[
(2 - x)^2 = 4 - 4x + x^2
\]

2. **Multiply by 5**:
\[
5(2 - x)^2 = 5(4 - 4x + x^2) = 20 - 20x + 5x^2
\]

3. **Combine the terms**:
Substitute back into the expression:
\[
20 - 20x + 5x^2 + xy - 2y
\]

4. **Rearranged expression**:
The final expression can be rearranged as follows:
\[
5x^2 - 20x + xy + 20 - 2y
\]

This is a simplified form of your original expression. If you have further manipulations in mind, such as factoring, differentiating, or solving for a variable, please provide me with that context!
