You can put this solution on YOUR website!
3X%5E2%2B3X=5
3X%5E2%2B3X-5=0
3X%5E2-12X%2B15X-5=0+ [-12X+15X=3X]
3X%28X-4%29-5%283X-1%29=0
%283X-5%29%28X-4%29%283X-1%29=0
from the above solution we can understand that,either
3X-5=0
3X=5
X=5%2F3...(1) or

X-4=o
X=4.....(2) or
3X-1=0
3X=1
X=1%2F3....(3)
hence the values (or cubes) are 5/3, 4, 1/3
