find three consecutive odd numbers such that the product of the smallest and the largest is 525
-------
1st: 2x-3
2nd: 2x-1
3rd: 2x+1
------
Equation:
(2x-3)(2x+1) = 525
4x^2-5x-3 -525 = 0
-----
4x^2 -x - 528 = 0
------
Factor:
(x-12)(4x+44)= 0
x = 12
--------------------
1st: 2x-3 = 21
3rd: 2x+1 = 25
