When you subtract 3xy^2 from 8xy^2, you will get the result 5xy^2. And so if you subtract 2xy^2 from 7xy^2, you will also get 5xy^2. So the answer is C. 7xy^2 - 2xy^2
8xy^2 - 3xy^2 Subtract Final Answer: 5xy^2
7xy^2 - 2xy^2 Subtract Final Answer: 5xy^2
The answer is C because both expression's results match.
