5a^2+6a+1

Both signs are +, so both of the signs in the factors must be plus. The constant term is 1, so the only possible integer factors are 1 and 1. So, so far we have:
(\ \ +\ 1))
The only way to make a 
is with a 
and an 
, so if this trinomial is factorable over the integers, the factors must be:
(a\ +\ 1))
Verification that this is the proper factorization is left as an exercise for the student.
