Question

Help,

Answer 1

@kirbykirby @ChipperJay*

Answer 2

You can just evaluate it by plugging in \(x=-2\) into the polynomial and you'll get the answer (since it's multiple choice)

Answer 3

D

Answer 4

yup :)

I mean you can d the long division method in which the remainder will be the answer, but it's probably longer to do and since it's multiple choice, why not use a faster solution :o ?

Answer 5

i know o.o can u help me with another

Answer 6

i put B. but its wrong. :/ dont understand

Answer 7

o.o that is strange... that should be the correct answer

Answer 8

i know o.O and it cant be A

Answer 9

i even double checked it on Wolfram Alpha

Answer 10

I dunno someone must have assigned the answer to the wrong letter :S because B is definitely right !

Answer 11

yeah, im going to pick A :S

Answer 12

the system gives you multiple tries?

Answer 13

twice, first time i picked letter B and it was marked wrong.

Answer 14

ah

Answer 15

well it would be good to bring this up to your teacher

Answer 16

yeah, i am going to email her.

Answer 17

ty kirby :)

Answer 18

im not sure about this one ^^

Answer 19

Ah this is an application of the Factor Theorem.

Essentially, if you find that when plugging in x=-4 and x=-1 and the polynomial evaluate to 0 (for both of these x values), then these x values are zeroes.

Answer 20

You can also think of it this way:
A zero is a value of x such that y=0 (the value that crosses the x-axis). So plugging in a value of x that is a zero, should give y=0

Answer 21

hmm A

Answer 22

yep =]

Answer 23

yayyy!!! :D

Answer 24

ty

Answer 25

yw!
