What is the product of 3 consecutive even integers if the middle integer is x?

Reiny
So your numbers would be
x2, x, and x+2 , (even numbers are 2 apart)
"product" is the result of multiplication, so
(x2)(x)(x+2)
= x(x^2  4)
or
= x^3  4x
check:
let the 3 numbers be 6,8, and 10, (so x = 8)
product = 6*8*10 = 480
from my formula: (8^3)  4(8) = 51232 = 480
