1per 2 x pangkat 4 di tambah 1per 3 x pangkat 3 dikurang 4x ditambah 5 dx

(1/2x^4 + 1/3x^3 - 4x + 5) dx
= (½x^-4 + ⅓x^-3 - 4x + 5) dx
= (½/(-4+1))x^(-4+1) + (⅓/(-3+1))x^(-3+1) - (4/2)x² + 5x + C
= (½/-3)x^-3 + (⅓/-2)x^-2 - 2x² + 5x + C
= (-1/6)x^-3 + (-1/6)x^-2 - 2x² + 5x + C
= -1/6x³ - 1/6x² - 2x² + 5x + C
