Question 473642
find the second of four consecutive even integers such that the product of the first and fourth integer will be the square of the second integer?
---
1st: 2x-2
2nd: 2x
3rd: 2x+2
4th: 2x+4
===============
Equation:
(2x-2)(2x+4) = (2x)^2
----
4x^2+4x-8 = 4x^2
4x-8 = 0
x = 2
---
2nd: 2x = 4
===================
