Step-by-step explanation:
if 3x-2 is a factor,
x=2/3 should be a root.
p(2/3)≠0.
hence, 3x-2 is not a factor of p(x)

Answer:
3x-2=0
3x=2
x=2/3
by putting value of x in the equation:
3*(2/3)³+(2/3)²-20*2/3+12
3*8/27+4/9-40/3+12
8/9+4/9-40/3+12
by taking LCM
(8+4-120+36)by 9
=-72/9
then divide -72 by 9
ur answer will be -8.
