Can somebody tell me what to do next for solving polynomial equations?

x^3 - 3x^2 -4x + 12= 0

I got the factors of 12 and i used 2.

(x+2) (x^2 + x + 12)=0

What do I do next?

    I used synthetic division to get (x+2)(x^2 + x + 12)=0

  • 12th grade -

    Factor x^2+x+12 now

  • 12th grade -

    therefore, (x+2)(x+4)(x+3)=0?

    x= -2, -4, -3?
