7a3 - a2 + 11 + (a3 - 2a2 - 5)

  • = 7a³ - a² + 11 + a³ - 2a² - 5
  • = 7a³ - a³ - a² - 2a² + 11 - 5
  • = 7a³ - a³ - a² - 2a² + 6
  • = 8a³ - a² - 2a² + 6
  • = 8a³ - 3a² + 6

5y2 - 3y - 4 - (2y2 - 3y + 7)

  • = 5y² - 3y - 4 - 2y² - 3y + 7
  • = 5y² - 2y² - 3y + 3y - 4 - 7
  • = 5y² - 2y² - 4 - 7
  • = 5y² - 2y² - 11
  • = 3y - 11

  1. 8a³ - 3a² + 6
  2. 3y - 11
