Bab Integral
Matematika SMA Kelas XI

₂
∫ (ax² - 6x + 5) dx = 15
⁻¹
                                   ₂
(a/3) x³ - (6/2) x² + 5x | = 15
                                   ⁻¹

((a/3) . 2³ - 3 . 2² + 5 . 2) - ((a/3) . (-1)³ - 3 . (-1)² + 5 . (-1)) = 15
(8a/3) - 12 + 10 + (a/3) + 3 + 5 = 15
(9a/3) = 15 - 6
3a = 9
a = 3
