2 Jawaban

  • 11p² - 17p + 24 - (2p² + 15p - 18) = 11p² - 17p + 24 - 2p² - 15p + 18
                                                         = 11p² - 2p² - 17p - 15p + 24 + 18
                                                         = 9p² - 32p + 42
  • = (11p² - 17p + 24) - (2p² + 15p -18)
    = 11p² - 17p + 24 - 2p² - 15p + 18
    = 11p² - 2p² -17p -15p + 24 + 18
    = 9p² -32p + 42
