Question

subtract the sum of (3xy-x^2y^2) and (3x^2y^2+xy-5) from (-15xy+x^2y2+7)​

Answer 1

Question :

Subtract the sum of (3xy-x^2y^2) and (3x^2y^2+xy-5) from (-15xy+x^2y2+7).

Solution :

= (-15xy + x²y² + 7) - [(3xy - x²y²) + (3x²y² + xy - 5)]

= (-15xy + x²y² + 7) - (4xy + 2x²y² - 5)

= -19xy - x²y² + 12.

Thank you.
