Factoring an equation

[kasd]

Hello. I've recently been trying to factor this equation but I really don't know where to start. Could you help me and show me the method of factoring these type of equations:
n^3+4*n^2-2*n-12
answer: (n+2)(n^2+2*n-6)

are you familiar with the rational root theorem?

Now that we've got an idea about how to sketch factored polynomials, taking into account the end behavior and the crosses, bounces, and slides at the x-axis, let's figure out how to deal with polynomials that start out in standard (un-factored) form.

I'll look at it. Thank you very much.
