Question

Find the product of three consecutive even integers ,if one of them is 2m.

Answer 1

Mletthe consecutive integers be 2m-1 , 2m , 2m +

Their product =

(2m-1)(2m-1)(2m)

(4m^2 - 1 ) 2m

8m^3-2m.

Answer 2

Let the consecutive even numbers be
2m,2m-2,2m+2
So their
Product=2m(2m-2)(2m+2)
Product=2m(4m*2-4)
Product=8m*3-8m
