Question

Identify the factors of the polynomial:
x^3+x^2-4x-4

Answer 1

Begin by separating
x^2 (x+1)-4(x+1)
Then write into two factors, one containing the initial pieces I factored out with and the other having (x+1).

Answer 2

ok

Answer 3

split it:\[(x^3+x^2)-(4x+4)\]factor out GCFs:\[x^2(x+1)-4(x+1)\]rearrange:\[(x^2-4)(x+1)\]the first binomial can be further split:\[(x+2)(x-2)(x+1)\]

Answer 4

okay thank you (x+2)(x-2)(x+1) is what I got

Answer 5

Nice job!
