Subtracting x2 - xy + y2 from 2xy - 3y2 + 2x2
1. First, let's write down the given expression: 2xy - 3y2 + 2x2 - (x2 - xy + y2)
2. Distribute the negative sign inside the brackets: 2xy - 3y2 + 2x2 - x2 + xy - y2
3. Combine like terms: 2x2 - x2 + 2xy + xy - 3y2 - y2
4. Simplify the expression: x2 + 3xy - 4y2
Therefore, the result when x2 - xy + y2 is subtracted from 2xy - 3y2 + 2x2 is x2 + 3xy - 4y2, which corresponds to option 'D'.
