Subtract: 4x2 - 5x2y + Y2 from - 3y2 + 5xy2 - 7x2 - 9x2y

Subtract: 4x² - 5x²y + y² from - 3y² + 5xy² - 7x² - 9x²y

Sum

4x² - 5x²y + y² from - 3y² + 5xy² - 7x² - 9x²y

= (- 3y² + 5xy² - 7x² - 9x²y) - (4x² - 5x²y + y²)

= - 3y² + 5xy² - 7x² - 9x²y - 4x² + 5x²y - y²

= - 3y²- y² + 5xy² - 7x2 - 4x² - 9x²y + 5x²y

= - 4y² + 5xy² - 11x² - 4x²y
