I'm not Totally sure but I'm pretty sure its B<span />
The answer is 2(x + 3)(x^2 + 1).
Steps:
2x^3 + 6x^2 + 2x + 6
2x^3 + 2x + 6x^2 + 6
2x(x^2 + 1) + 6(x^2 + 1)
(2x + 6)(x^2 + 1)
2(x + 3)(x^2 + 1)
The answer is D.
You cannot factorise it as there are two different terms being squared with the middle term containing both. Also, if you expand any of the brackets in the questions you will not get the original equation so non of them are right so it has to be D. :)
To find the number of notebooks Steve bought you will subtract the amount he paid for his backpack from the total amount, and then you will divide the remaining amount by $3.98 to find the number of notebooks.

$15.92/$3.98
4
