Question

Use the grouping method to factor x^3 + x^2 + 5x + 5

Answer 1

X^2(x+1)+5(x+1)

(x^2+5)(x+1)
the answer is a

Answer 2

Answer:

(x + 1) (x^2 + 5)

Step-by-step explanation:

Simplify the following:

x^3 + x^2 + 5 x + 5

Factor terms by grouping. x^3 + x^2 + 5 x + 5 = (x^3 + x^2) + (5 x + 5) = x^2 (x + 1) + 5 (x + 1):

x^2 (x + 1) + 5 (x + 1)

Factor x + 1 from x^2 (x + 1) + 5 (x + 1):

Answer:  (x + 1) (x^2 + 5)
