Question

what remainder do you get when you divide x^100-2x^49-1 by (x+1)

Answer 1

oh i hate this

Answer 2

I am just gonna solve it

Answer 3

I think 2^49

Answer 4

I am just gonna check that out

Answer 5

how do you solve it..i need to know for testing

Answer 6

ok

Answer 7

so basically you plug in -1 into the equation and the number you get is the remainder

Answer 8

I'm gonna have to brush up my algebraic division skills. Gimme a sec.

Answer 9

(-1)^100-2(-1)^49-1=2^49

Answer 10

why -1 though

Answer 11

Yeah, rld613, I'm afraid you may be thinking of something else entirely. What you're describing is not algebraic division.

Answer 12

Its the reamainder theorem for polynomiials

Answer 13

basically the way i wld explain it

Answer 14

so the poly nomial is being divided by (x+1)

Answer 15

rld im still confused as to why we elected to replace x with -1

Answer 16

Oh this is confusing

Answer 17

So i will just give u a tip and won't explain y but you take the oppostie value of the constant

Answer 18

So over here it is being factored by (x+1)
The constant is 1 so swith the sign and it is -1

Answer 19

Okay, so as it turns out, Jim and rld613 are right! It's been forever since I did one of these. Thanks for the brain teaser!

Answer 20

rld are you free tonight...you have been explaining things to me wonderfully and i have a boatload of questions remaining lol

Answer 21

Lets say you were dividing the polynomial by (x+3) what would you plug into the polynomial to find the remainder

Answer 22

I actually have to finish writing a term paper!!!!

Answer 23

ohh alright

Answer 24

but wld be the answer to the question I asked

Answer 25

are u there?

Answer 26

hmm ive got 5

Answer 27

you got 5 for what?

Answer 28

I was asking what number would you plug into the polynomial to find th eremainder

Answer 29

oh -3

Answer 30

i pluged -3 and solve and got 5

Answer 31

ya u got it and the answer yo uget is the remainder

Answer 32

no it isn't 5

Answer 33

(-3)^100-2(-3)^49-1

Answer 34

5^47

Answer 35

it like this huge number

Answer 36

yea its like 5.1537752027E47

Answer 37

ya

Answer 38

that is a huge number

Answer 39

which of the following numbers is not a potential rational zero of the polynomial funcion

p(x) = x^4 - 9x^2 - 4x + 12

Answer 40

what is a potentional rational 0

Answer 41

ok i think i know what to do

Answer 42

x^100-2x^49-1 by (x+1) notice that in between the terms there are 51 then 49 so both powers of 1 will be odd
