1.∫(2x-3)(3x+2)dx
=∫ 6x²+4x-9x-6 dx
= 6/3 x³ -5/2x² -6x +c
=2x³ -5/2x² -6x +c.............E
2.∫²batas bawah0 2x(8-x²)dx
=∫²batas bawah0 16x-2x³ dx
= 16/2 x²-2/4x pangkat 4
=8x² -1/2 xpangkat 4
=8(2)²-1/2(2)pangkat 4 - 0(krn dikalikan 0)
=32-8
=24.........................D
3.∫ batas atas b,batas bawah 1 (2x-3)dx=12
2/2x²-3x=12
x²-3x=12
(b)²-3(b)-{(1)²-3(1)}=12
b²-3b+2=12
b²-3b=12-2
b²-3b=10
(5)²-3(5)=10(jawabannya 5).............B
