Answer:
(2x +1)
Step-by-step explanation:
The first term in the trinomial is the product of first terms, so the missing factor's first term will be ...
2x^2/x = 2x
The last term (constant) in the trinomial is the product of last terms, so the missing factor's constant is ...
6/6 = 1
The missing linear factor is (2x +1).
