Question

Simplify (-12x^4)/(x^4+8x5)

Answer 1

\[-\frac{ 12 }{ 8x+1 }\]

Answer 2

what is x not = to

Answer 3

Distribute the \[-12x ^{4}\] to each of the parts of the other area.

So you'll get this as a result
\[(x ^{4}*-12x ^{4}) + (8x ^{5}*-12x ^{4})\]
(I'm assuming your 8x5 meant an exponent.

Then simplify. Do you know how to do that part?

Answer 4

not really

Answer 5

Woah, sorry, ignore that, I just saw that / in there. My fault.

Answer 6

and yes it did sorry

Answer 7

and can you tell me is x not = to 0

Answer 8

or can it be 0

Answer 9

the question is not done unless it have an equal sign

Answer 10

?

Answer 11

is that the right problem

Answer 12

What you would do is separate the denominator to 2 fractions essentially.

So you would have \[\frac{ -12x ^{4} }{ x ^{4} } + \frac{ -12x ^{4} }{ 8x ^{5} }\]

You would then simplify.
And Marv93w is right, you can't find out what x is equal to unless you have the rest of the equation. It's impossible to solve this, only to simplify it.

Answer 13

Simplify (-12x^4)/(x^4+8x^5)

Answer 15

I still need help

Answer 16

I think I get it.
So what your question is is to simplify it and then determine if x can be 0?

Answer 17

yes

Answer 18

I got you started on the simplification, do you know how to do the next step? What do you get if you try it?

Answer 19

what are the answer choice

Answer 20

First, do the simplification so you know which set of questions you have.
Then, plug in the values given. If you can get a number for a solution then it can be that number. For example, in c, x can't equal 0 because then the denominator would be 0, and you can't divide by 0.

Answer 21

the answer look like it d if you plug in 1 with the question

Answer 22

Marv93w provided you the correct simplification on the first post.

Answer 23

it is thank you are you sure and @PsychoTink is he right I want for you to tell me is that right is it D

Answer 24

1 + 8x must not = 0
So what must x not equal???

Answer 25

i see it look like it asking for the domian

Answer 26

@Marv93w how are you saying the answer is D. That's not possible.
@s17 the goal of this site (per the code of conduct) is NOT for people to just give the answer, but to help you find the answer on your own and know how to find it.

Answer 27

It is not D

Answer 28

If the denominator is 8x+1, the answer can't be a denominator of 9.

Answer 29

x=-1/8

Answer 30

@radar I like your dog and I know I do want help

Answer 31

this is hard for me I am really good at biology not math

Answer 32

Thanks, Marv93w shows you that x can not = - 1/8, because if it does then the denominator becomes 0 and division by 0 is a no no

Answer 33

okay so is it C

Answer 34

so you are saying its B

Answer 35

Not C

Answer 36

because if it can not be 1/8 and not 0 its B

Answer 37

It is what Marv93w posted in the very first post below your submitted problem.

Answer 38

you have to put the full question in order to answer the problem

Answer 39

thanks and again I like your dog I love dogs :) haha thanks again

Answer 40

Simplify x=7/x^2+4x-21
