Tolong di jawab ya kak soal tentang integral, karang sudah di kumpulkan

4) (2x³ - x²) 4 dan 1
= (2(4)³ - 4²) - (2(1)³ - 1²)
= (2(64) - 16) - (2 - 1)
= 128 - 16 - 1
= 111

5) x²(x³ - 8x) dx
= (x^5 - 8x³) dx
= (1 / 5+1)x^(5+1) - (8 / 3+1)x^(3+1) + C
= (1/6)x^6 - 2x⁴ + C

6) (2x -2)(3x+1) dx
= (6x² - 4x - 2) dx
= (2x³ - 2x² - 2x) 3 dan 2
= (2(3)³ - 2(3)² - 2(3)) - (2(2)³ - 2(2)² - 2(2))
= (2(27) - 2(9) - 6) - (16 - 8 - 4)
= 54 - 18 - 6 - 4
= 26
