Answer:
8x² + 7xy - 6y² + 4x²-3xy + 2y² + (x²+
xy - y²)
=> 8x² + 7xy - 6y² + 4x²-3xy + 2y² - 4x² + xy-y²
=> 8x² + 4x² - 4x² + 7xy - 3xy + xy - 6y² +
2y²-y²
=> 8x² + 5xy - 3y²

Answer:
Step-by-step explanation:
We can add these expressions by combining the like terms:
(8x^2 + 4x^2 - 4x^2) + (7xy - 3xy + xy) + (-6y^2 + 2y^2 - y^2)
Simplifying, we get:
8x^2 + 5xy - 5y^2
Therefore, the sum of the given expressions is 8x^2 + 5xy - 5y^2.
