Hee hee this one will take a bit.

Answer 3

Thanks Sandra =) Anyone else have experience factoring this?

Answer 4

Don't know this really.

Guess you can forget minus numbers cos you always end up minus.

So 1, 2, 4, 1/3, 2/3, 4/3 if I understood that Wiki page correctly.

Answer 5

the rational root thrm says to find a pool of options; simply factor the last # over the first #

1,2,4
+- ----- ; now form all the numbers you can from these and anything that repeats
1,3 is just redundant

Answer 6

+-(1, 2, 4)
+-(1/3, 2/3, 4/3)

Answer 7

If it can be factored into rational roots; and not those radical things, this will be the option to do it
