Question

Are these correct? Please explain if not :)

Answer 1

Professor McCoy: She says that 2 is a zero of g(x) because long division with (x results in a remainder of 0.
Ms. Guerra: She says that 2 is a zero of g(x) because g(2) = 0.
Mr. Romano: He says that 2 is a zero of g(x) because synthetic division with 2 results in a remainder of 0.

Answer 2

Can you reference any theorems that support your explanations??

Answer 3

graphing? lol, nah i think that's it

Answer 4

btw, all three people are correct

Answer 5

lol so do you know if they all are right or not?

Answer 6

oh lol thank you! :)

Answer 7

do you know how they are right?

Answer 8

your answers r right

Answer 9

Thanks! :) Could you explain how you knew this tho?

Answer 10

factor theorem

Answer 11

Thank you very much. (:

Answer 12

???

Answer 13

What happen?

Answer 14

pellet happens

Answer 15

wtf?

Answer 16

? im confused ?

Answer 17

I typed s.h.i.t happen and it changed to pellet happen

Answer 18

The first one can not be evaluated. You typed:
"Professor McCoy: She says that 2 is a zero of g(x) because long division with (x results in a remainder of 0."
That doesn't make sense. Did you mean (x -2) or (x + 2).. The difference is important

Answer 19

It is what my teacher gave me and i didnt know if it was right or not. As well as how to explain to her on why i felt it wasnt or was...

Answer 20

@xxferrocixx oh lol

Answer 21

" .... (x ......" with no closing parenthesis is obviously a typo. The mystery is should it have been
(x + 2).....that would be wrong
or
(x - 2)...that would be correct

Answer 22

:/ aw so i will just skip that and tell her it had a typo :)

Answer 23

Yes.....Just x alone is incorrect, too. You would have to do long division with (x - 2) to show that 2 is a zero.

Answer 24

The other 2 look good.

Answer 25

So for that i would say that just x alone is incorrect and it doesnt need a theorem?!

Answer 26

And for the others i would say yes it is correct and what theorem do you use to figure it out ?

Answer 27

I doubt your teacher meant to put x alone there as he/she wouldn't have bothered to put that opening "(" there if it were gonna be just x alone.

Answer 28

I will point it out to her :)

Answer 29

But for the others what theorem would i give to say this is how you would solve? Would it be long division??

Answer 30

@BangkokGarrett ??

Answer 31

g(2) = 0 follows the rule that a function of a constant is the equal to the constant
f(x) = 0 is zero
g(3) = 2 is 2
t(4) = 3 is 3
so the rule states

long division and synthetic division are some of the ways to solve for the root for quotient functions f(x) = g(x)/h(x)

Answer 32

@Loser66 did I make a mistake? laughing out loud correct me of any wrong, I just woke up and a bit groggy

Answer 33

Thank you! :) @nincompoop

Answer 34

I didn't follow so I don't know whether you are right or wrong, sorry for the slow net

Answer 35

:) thank you tho it helped !
