How do you factorize this polynomial completely:

f(x) = 3x^3 + 7x^2 - 2x - 8

Please explain in steps.

Wow...why wasn't that around when I was in H.S....that's fuckin incredible! LOL

I'm completely incapable of math. Aside from any electrical formula which I need to know for my job.

Great One said:
Who the fucks your teacher? They didn't tell you about the quadratic formula..?http://en.wikipedia.org/wiki/Quadratic_equation

Factor out the x and plug the shit in there, ax^2+bx+c.

Argh. I know the Quadratic Formula, studied that like three years ago.

But how the fuck can you use the Quadratic Forumla on POLYnomials? It isn't second degree, it's third degree ya' know. Not ax^2+bx+c it's ax^3+bx^2+cx+d.

By the way, on vacation for a week now, tried to study polynomials that they were studying in college right now but I just don't seem to understand it.

And google isn't helping me either.

i dnt get it, u want the derivative?

f' (x) = 9X^2 + 14X -2

since its a FUNCTION they're both equal...

edit-

f'' (x) = 18X + 14

f''' (x) = 18
