%287x%5E2+-+xy+%2B+y%5E2%29+%2B+%28-x%5E2+-4xy+%2B+5y%5E2%29 Start with the given expression.


%2B%287x%5E2-x%5E2%29%2B%28-xy-4xy%29%2B%28y%5E2%2B5y%5E2%29 Group like terms.


6x%5E2-5xy%2B6y%5E2 Combine like terms.


So %287x%5E2+-+xy+%2B+y%5E2%29+%2B+%28-x%5E2+-4xy+%2B+5y%5E2%29=6x%5E2-5xy%2B6y%5E2
