(2p + 3)² - (2p - 3)²

1 Jawaban

  • (2p + 3)^2 - (2p - 3)^2
    = (2p + 3) - (2p - 3)
    = 4p^2 - 6p - 6p - 9
    = (4p^2 - 12p - 9) - (4p^2 - 12p - 9)
    = -16p^4 - 480p^3 - 36p^2 + 48p^3
    + 144p^2 + 108p + 36p^2 + 108p + 81
    = -16p^4 - 480p^3 + 48p^3 - 36p^2 + 144p^2 + 36p^2 + 108p + 108p + 81
    = -16p^4 - 432p^3 + 144p^2 + 216p + 81
