@zoomiemoo , can you please help me?

- anonymous

@whydude81 , would you help too? pls <3

- anonymous

is it -12x^4/(x^4+8x^5)

- anonymous

To solve this we can start by breaking it up

- anonymous

-12x^4/x^4 = -12

- anonymous

how do we break it up?

- anonymous

-12x^4/8x^5 = -3/2x

- anonymous

-3/(2x)

- anonymous

Is that the answer?

- anonymous

no. now we have to put the parts back together (-12 + -3/(2x)) or (-12/ + -12/(8x) this equals -12/1+8x

- anonymous

How did you do that? I have a lot of problems like this one.

- anonymous

additionally anything that will make the the bottom of the fraction 0 will not be a solution so x cannot equal 1/8 however 0 can be a solution because the bottom still equals 1 when x = 0

- anonymous

I moment I have another student how needs assistance

- anonymous

I am back

- anonymous

let me right it out give me a moment

- anonymous

Okay, thank you. So is it -12/1+8x where x does not equal -1/8 or is it -12/1+8x where x does not equal -1/8,0 ?

- anonymous

Okay, thank you.

- anonymous

x can equal 0 because the denominator will equal 1 which will give you a solution answer is A

- anonymous

Would you still like me to explain the problem again

- anonymous

Yes, please :)

- anonymous
