### Instruction: Find all roots of the polynomial $x^3+x^2-4x-4$. Enter your answer as a list of numbers separated by commas.### Response: First let's factor $x^3+x^2-4x-4$.
Ok, well $x^3+x^2$ can be factored as $x^2(x+1)$.
And $-4x-4$ can be factored as $-4(x+1)$.
So $x^3+x^2-4x-4$ can be factored as $(x^2-4)(x+1)$.
And $(x^2-4)$ can be factored as $(x+2)(x-2)$.
So $x^3+x^2-4x-4$ can be factored as $(x+2)(x-2)(x+1)$.
