Question

Factor completely 2x3 + 4x2 + 6x + 12.

Answer 1

2x^2(x+2) +6(x+2) = (2x^2 +6)(x+2) = 2(x^2 +3)(x+2)

so this mean that the 4th choice will be right sure 

Answer 2

Answer:

$2[(x^2+ 3)(x + 2)]$

Step-by-step explanation:

Given : $2x^3 + 4x^2 + 6x + 12$

To Find: factor Completely

Solution:

$2(x^3 + 2x^2 + 3x + 6)$

Taking 2 as common

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

Now factorizing further

$2[(x^2+ 3)(x + 2)]$

So, the factored form of $2x^3 + 4x^2 + 6x + 12$ is $2[(x^2+ 3)(x + 2)]$

Hence Option D is correct.
