Ciara Moran · Answer 1

Step-by-step explanation:

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

= (x + 1) (x² + 3)

Salty · Answer 2

(x+1) (x^2+3)

Step-by-step 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)
