P(x) = 3x³ - 4x² - ax + 2 , habis dibagi 3x+2
3x+2 = 0--> x= - 2/3
P(-2/3) = 0
3(-2/3)³ - 4(-2/3)² - a(-2/3) + 2 = 0
3(-8/27) - 4(4/9) + 2/3 a + 2 = 0 ..kalikan 27
-24 - 48 + 18a + 54 =0
18 a= 18
a = 1

f(x)= 6x³ + 7x² + px - 24
x = 3/2
f(3/2) = 0
6(3/2)³ + 7 (3/2)² + p(3/2) -24 =0
6(27/8) + 7(9/4) + 3/2 p - 24 =0 ...kalikan 8
162 + 126 + 12p - 192 =0
12p = -96
p = -8
