If n is an integer, what is the remainder when `3x^(2n+3)-4x^(2n+2)+5x^(2n+1)-8` is divided by x+1 ?

A

-20

B

-10

C

-4

D

0

Text Solution

Verified by Experts

The correct Answer is:
A

According to the Remainder Theorem, simply substitute -1 for x. Since2n+3 and 2n+1 are odd , and 2n+2 is even, this substitution yields `3(-1)-4(1)+5(-1)-8=-20`. [4]
