<PRE><B>Question 853149</B>
The house addresses of two neighbouring houses differ by two. Their product is 85 263. What is each address?

----------
1st: x-1
2nd: x+1
-------------------
Equation:
(x-1)(x+1) = 85,263
------
x^2 - 1 = 85,263
--------
x^2 = 85,264
---------
x = 292
-----
x-1 = 291
x+1 = 293
