Question

use the grouping method to factor this polynomial.

Answer 1

the correct answer is C

Answer 2

Answer:

C. $(x^2 + 3)(x + 3)$

Step-by-step explanation:

Hello!

We can group the first two terms and the last two terms and factor each group.

Factor by Grouping

• $x^3 + 3x^2 + 3x + 9$
• $(x^3 + 3x^2) + (3x + 9)$
• $x^2(x + 3) + 3(x + 3)$

Now we can combine the like factors:

• $(x^2 + 3)(x + 3)$

The answer is Option C.
