Answer:
I think it's simple sentence
did this answer your question...no. OK well that is your loss
I'm assuming that y2 means y^2 or y squared. In that case, your factors will be (6y+1) and (6y-1).
You haven't provided any value, but I can tell you the solution set for the inequality.

Add 3x to both sides:

Add 6 to both sides:

Which is of course equivalent to

Divide both sides by 9

So, every number smaller than 2 is part of the solution of this inequality.
