Answer: 9x + 4x²
Explanation:
1) Length = 14x - 3x² + 2y
2) Width = 5x - 7x² + 7y
3) Length - width = [14x - 3x² + 2y] - [5x - 7x² + 7y]
4) Calculate:
i) Distribute the negative sign in front of the second polynomial:
14x - 3x² + 2y - 5x + 7x² - 2y
ii) Combine like terms:
9x + 4x²
5) Answer: 9x + 4x²
