Answer:

D.

Step-by-step explanation:

When you take out an x it gives an equation you can factor.

anonymous12345678901
so first group them

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

Then factor out the gcf of both groups

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

Since the stuff in the parentheses are the same for both groups, we can just put the stuff outside together and leave the (x+1) as a factor

So your final solution:

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