A. 82
B. 92
C. 102
D. 106
E. 120

Jawaban : C

_-1∫² (5x + 1) (3x + 5)  dx
_-1∫² (15x² + 25x + 3x + 5)  dx
_-1∫² (15x² + 28x + 5)  dx
= [5x³+ 14x² + 5x + C]_-1²
= 5.2³+ 14 2² + 5.2 + C - (5. (-1)³+ 14 . (-1)² + 5 . (-1) + C)
= 5.8 + 14.4 + 10 + C - ( -5 + 14 -5 +C)
= 40 + 56 + 10 + 5 - 14 + 5
= 102
