the product of two consecutive positive integers is 19 more than their sum. what are the integers
----
1st: x
2nd: x+1
-------------
Equation:
x(x+1) = x+x+1 + 19
---
x^2 + x = x + x+1 + 19
---
x^2 = x+20
---
x^2 -x -20 = 0
----
Factor:
(x-5)(x+4) = 0
x = 5 or x = -4
----
If x = 5
x+1 = 6
-----------------
If x = -4
x+1 = -3
==================
cheers,
