Find all integers b for which a^2 + ba - 50 can be factored.
-------------
Need two numbers whose product is -50 and whose sum is "b":
---
Products are
1*-50 with sum = b = -49
-1*50 with sum = b = 49
---
2*-25 with sum = b = -23
-2*25 with sum = b = 23
----
-5*10 with sum = b = 5
5*-10 with sum = b = -5
---
Those are the possible values of b if
you limit b to being an integer.

-1 + 50 = 49
1 - 50 = -49
-2 + 25 = 23
and so on until you have considered all of the integer factors of -50
