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
(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
