9. Hasil dari ₀∫³ (x + 3) (x - 2)  dx = ...

A. 5 1/2
B. 5 1/3
C. - 4 1/2
D. - 4 1/3
E. - 4 1/6

Jawaban : C

(x + 3) (x - 2)
= x² - 2x + 3x - 6
= x² + x - 6

₀∫³ (x² + x - 6)  dx
[1/3 x³ + 1/2 x² - 6x + C]₀³
= 1/3 3³ + 1/2 3² - 6. 3 + C- (1/3 0³ + 1/2 0² - 6. 0 + C)
= 9 + 9/2 - 18
= - 9 + 9/2
= - 9/2
= - 4 1/2
