In order to get through this problem, one can multiply out the answers offered.
Try the 3rd one down the list first.

you can check by multiplying, lets try (2x+1) (x+2)
so 2x (x)  = 2x^2
2x (2) = 4x
1(x) = x
1(2) = 2
so that is 2x^2 + 5x + 2  that is what we were looking for

@ivettef365 You should have done one that wasn't the answer, so the questioner would be challenged to do it his/herself.
