Question

PLEASE EXPLAIN

Which of the following polynomials has x+2 as a factor?

A) x^2 +4
B) x^2 -2x +1
C) 2x^2 -2x +1
D)x^3-6x^2+11x-6
E) 2x^2 + 10x^2 +10x -4

Answer 1

is this a flvs Q?

Answer 2

a what Q???

Answer 3

sorry Q=question

Answer 4

I know but fivs Q??
what you mean by that???

Answer 5

Florida virtual school = flvs is this a question off of their site if so can you tell me what number lesson

Answer 6

no it isnt

Answer 7

okay 1 sec

Answer 12

if x+2 is a factor then x=-2 is a zero
see for which polynomial when you plug in -2, gives you a result of 0

Answer 13

I bet one of your choices is a tyoe-o
and I think I know which one :)

Answer 14

which one?

Answer 15

Look at your choices and you tell me which one looks like you have like terms.

Answer 16

A) x^2 +4
B) x^2 -2x +1
C) 2x^2 -2x +1
D)x^3-6x^2+11x-6
E) 2x^2 + 10x^2 +10x -4

These are the choices you posted...
Do you see a type-o?
Look at the choice that has like terms.

Answer 17

Is the last choice really suppose to have so many x^2 's?

Answer 18

anyways
I think it should be:
A) x^2 +4
B) x^2 -2x +1
C) 2x^2 -2x +1
D)x^3-6x^2+11x-6
E) 2x^3 + 10x^2 +10x -4

now just evaluate each of those at x=-2
and see which outputs 0
and that will be your answer

Answer 19

None of the polynomials have x+2 as a factor.
Refer to the attached result from the Mathematica 9 program.

Answer 20

what the heck are you talking about

Answer 21

@freckles you're right

Answer 22

this is why one of the choices is a type-o
I think the type-o is in E
because when you replace the x's with -2's in 2x^3+10x^2+10x-4
you get???

Answer 23

I plugged -2 in all of them and E was the answer, and that's the correct answer

there's no tyop

Answer 24

I get 0

Answer 25

right
but there was a type-o @Romwil in the original question

Answer 26

you have 2x^2+10x^2+10x-4

Answer 27

as choice E

Answer 28

I guess

Answer 29

but either or that's how you solve it right?

Answer 30

yep you just look for which outputs 0 for x=-2
that is how you solve it (or I believe is the quickest way anyways)

Answer 31

it isn't the only way
just the quickest in my opinion
