You can put this solution on YOUR website! Find three consecutive negative integers such that 3 times the product of the first and third exceeds twice the product of the first and second by 32.
-----------------
Let the integers be x, x+1, x+2
------------
3x(x+2)-32=2x(x+1)
3x^2+6x-32 = 2x^2+2x
x^2+4x-32=0
(x+8)(x-4)=0
x=-8
x+1=-7
x+2=-6
