Answer:
C. [tex](x^2 + 3)(x + 3)[/tex]
Step-by-step explanation:
Hello!
We can group the first two terms and the last two terms and factor each group.
Factor by Grouping
- [tex]x^3 + 3x^2 + 3x + 9[/tex]
- [tex](x^3 + 3x^2) + (3x + 9)[/tex]
- [tex]x^2(x + 3) + 3(x + 3)[/tex]
Now we can combine the like factors:
- [tex](x^2 + 3)(x + 3)[/tex]
The answer is Option C.
