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. =/

**Count Iblis**, Thursday, December 4, 2008 at 7:26pm9x^3 + 9x + 30x^2 =

x [9 x^2 + 30 x + 9]

Then x = 0 or 9 x^2 + 30 x + 9 = 0

Divide by 3:

3 x^2 + 10 x + 3 = 0

(3 x + 1)(x + 3) = 0

x = -3 or x = -1/3
