1. If the product of two consecutive odd integers is 783, what is the sum of their squares?
1st: 2x-1
2nd: 2x+1
---
Equation:
4x^2-1 = 783
4x^2 = 784
x^2 = 196
x = 14
---
1st: 2x-1 = 27
2nd: 2x+1 = 29
====================================
2. The difference between the squares of two consecutive positive integers is 2013. What is the larger integer?
1st: x
2nd: x+1
----
Equation:
(x+1)^2 - x^2 = 2013
2x+1 = 2013
2x = 2012
x = 1006
------
x+1 = 1007
------------------------

1. If the product of two consecutive odd integers is 783, what is the sum of their squares?
--------------
sqrt(783) =~ 28, the center
--> 27 & 29
27^2 + 29^2 = 1570
==============
2. The difference between the squares of two consecutive positive integers is 2013. What is the larger integer?
--------
(n+1)^2 - n^2 = 2013
n = 1006
