Answer:

Addition of Polynomials

1. (-7xy + x²) + (y² + 5xy)

  • N. x² - 2xy + y²

2. (4xy + x²y - 5) + (12x²y - 5 - 8xy)

  • D. 13x²y - 4xy - 10

3. (x³ - 1) + (9 + 6x + x³)

  • E. 2x² + 6x - 8

4. (5xy - x² - 4y²) + (7y² - 12xy + 3x²)

  • T. 2x² - 7xy + 3y²

5. (3x² + x - 3) + (5 - x² - x)

  • A. 2x² + 2

Subtraction of Polynomials

6. (11a - 4a²) - (16 - a²)

  • S. -3a² + 11a - 16

7. (5a² + 13ab - 4b²) - (4a² + 11ab - b²)

  • I. a² + 2ab - 3b²

8. (6a² - 9a - 5) - (2a² + 5)

  • M. 4a² - 9a - 10

9. (2b² + 4ab - 2a²) - (-3a² - b²)

  • R. a² + 4ab + 3b²

10. (2a² - 4ab + 3b²) - 2ab

  • O. 2a² - 6ab + 3b²
