factor completely.
$x^3 + 5x^2 - 2x - 10$
answer: attempt 1 out of 20

Explanation:

Step1: Group terms

Group the first two terms and the last two terms: $(x^3 + 5x^2) + (-2x - 10)$

Step2: Factor out GCF from each group

Factor out $x^2$ from the first group and $-2$ from the second group: $x^2(x + 5) - 2(x + 5)$

Step3: Factor out common binomial

Factor out $(x + 5)$: $(x + 5)(x^2 - 2)$

Answer:

$(x + 5)(x^2 - 2)$
