Need help solving unequality

[Nacelunk]

Hi, first of all I am in grade 11 math so probably for you it will seem kinda easy unlike for me (well, when you know how to solve something it's always easy).

Here. This is the most I could simplify it to. Solve for x:

5x^3+6x^2+2x > 9. And please show the steps.

I have to dig back in to my memory bank, but I think you would start by subtracting 9 from both sides. Then try factoring, and go from there. Let me know how that works out.
