Semoga membantu ya dan selamat belajar.Kelas : XII
26). int bts ats 4 bwah 2 (x - 2)(x + 4) dx
= int (x²+2x-8) dx
= [1/3x³ + x² - 8x] bts ats 4 bwah 2
= [1/3(4)³ + (4)² - 8(4)] - [1/3(2)³ + (2)² - 8(2)]
= [1/3(64) + 16 - 32] - [1/3(8) + 4 - 16]
= [16/3] - [-28/3]
= 44/3 atau 14(2/3) → Merupakan nilai integralnya
