Question

Use the grouping method to factor x3+ x2 + 3x + 3.

Answer 1

Answer:
(x+1) (x^2+3)
Explanation:
x^3 + x^2 + 3x + 3
Factor an x^2 out of the first group of 2 terms and a 3 out of the last group of 2 terms
x^2 (x+1) +3(x+1)
Now factor out an (x+1)
(x+1) (x^2+3)

Answer 2

Explanation:

x³+ x² + 3x + 3 = x² ( x + 1) + 3 ( x + 1)

=( x + 1)(x² + 3)
