I need to find the value of x.

9x^3 + 9x = 30x^2

It's confusing because apparently I have to do 9x^3 + 9x and then add the + 30x^2 to it, and then make it equal 0, so it ends up like this:

9x^3 + 9x + 30x^2 = 0

And afterward, I would factor it. How do you factor it?

I'm having trouble factoring in general. =/
