Soal Ujian Matematika IPA Kelas 12
Tahun 2016Soal Pilihan Ganda
32. Hasil dari 0 ∫ 23(x+1)(x-6) dx =
A. -58
B. -56
C. -28
D. -16
E. -14
Jawaban : A
= 0 ∫ 23(x2 - 5x - 6) dx
= 0 ∫ 2(3x2 - 15x - 18) dx
= [ x3 - 15/2x2 - 18x + c]0 2
= [ x3 - 15/2x2 - 18x + c]0 2
= 23 - 15/2 . 22 - 18.2 - (03 - 15/2 . 02 - 18. 0 + c)
= 8 - 15/2 . 4 - 36
= 8 - 30 - 36
= -58
= 8 - 15/2 . 4 - 36
= 8 - 30 - 36
= -58
