Yep and you should start by "guessing a number" that is either (-1,1,2,-2,3,-3,6,-6). Why these numbers ? Well 6 can be divided by these numbers. Let's say that number is 6. Then perform an Euclidian devision in which you divide the given expression by (x - 6). What you get is an expression of second degree in x times (x-6) equals the given expression. This should get you startedarildno said:

Don't bother to help OP, marlon.
In another thread, he has refused even to do a single thing on his own with the expression 18t^2-2.
He is just after having his homework done for him.
