Question

Suppose 3s represents an even integer. What polynomial represents the product of 3s, the even integer that comes just before 3s, and the even integer that comes just after 3s?

a. 27s3 + 12s
b. 27s3 - 3s
c. 27s3 - 12s
d. 3s3 - 12s

Answer 1

The answer is C i just toke the test. good luck.

Answer 2

If 3s is an even integer, the even integer that comes just before 3s is 3s-2, and the even integer that comes just after 3s is 3s+2.

The product of the integers:

`3s(3s-2)(3s+2)= \\ 3s ((3s)^2-2^2)= \\ 3s(9s^2-4)= \\ 27s^3-12s`

The answer is C.
