The product of two positive consecutive odd integers is 399. The sum of these two integers is:
--------------
1st: 2x+1
2nd: 2x+3
-------------
EQUATION:
(2x+1)(2x+3) = 399
4x^2+8x+3 = 399
4x^2+8x-396 = 0
2x^2+4x-198 = 0
x=9 or x = -11
-------------------
2x+1 = 19 or -21
2x+3 = 21 or -19
--------------------
The sum is either 40 or -40
