Answer:
To add the expressions -2x² + xy - 5x² + 2xy and 4x² - 7xy, we combine like terms:
(-2x² + xy - 5x² + 2xy) + (4x² - 7xy)
Combine the x² terms:
(-2x² - 5x²) + (4x²) = -7x² + 4x² = -3x²
Combine the xy terms:
(xy + 2xy - 7xy) = -4xy
The final expression is:
-3x² - 4xy

Answer:
3x²-4xy
Step-by-step explanation:
2x²+xy+5x²+2xy+4x²-7xy
Arrange the like terms
2x²+5x²+4x²+xy+2xy-7xy
= 3x²-4xy
