Question 131064
The product of two consecutive integers is 360. Find the integers.
--------------------
I think you need consecutive EVEN integers.
---------------------
1st: 2x
2nd: 2x+2
------------
EQUATION:
2x*(2x+2) = 360
4x^2+4x-360 = 0
x^2 + x -90 = 0
x = [-1 +- sqrt(1-4*-90)]/2
x = [-1 +- sqrt(361)]/2
x = [-1 +- 19]/2
x = [18/2] or [-20/2]
x = 9 or -10
---------------
2x = 18 and 2x+2 = 20
OR
2x -20 and 2x+2 = -18
