To find the factors of the expression
, we can use polynomial long division or synthetic division to divide the expression by one of the factors and see if we get a quadratic expression. Let's try dividing by
:
The quotient is
, which is a quadratic expression. Now, we can factor this quadratic expression:
So, the factors of the original expression
are
,
, and
. Therefore, the correct choices are:D
