Question

Use the grouping method to factor this polynomial.

Answer 1

the correct answer is C

Answer 2

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

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.
