The product of two consecutive odd whole numbers is 143. Find the numbers.
----
1st: 2x-1
2nd: 2x+1
------
Equation:
(2x-1)(2x+1) = 143
4x^2 -1 = 143
----
4x^2 - 144 = 0
Factor:
(2x-12)(2x+12) = 0
x = 6 or x = -6
-----
If x = 6:
1st: 2x-1 = 11
2nd: 2x+1 = 13
----
If x = -6:
1st: 2x-1 = -13
2nd: 2x+1 = -11
