by
4x^2 – 4x + 1

Answer 1

You need the answer with the work or just the answer?

Answer 2

with work

Answer 3

Alright, give me three minutes!

Answer 4

ok thank you soooooooo much!!

Answer 5

No problem. I hate it when I post a question and it never gets answered, so I don't do that the people. I also know how it feels. :)

Answer 6

-12x^3 – 8x^2 + 17x – 5
------------------------
4x^2 – 4x + 1
-12x^3 - 4x^2 + 13x - 4

Is that what you were looking for?

Answer 7

@jdorta1, are you still here?!?!

Answer 8

sorry it keeps freezing on me

Answer 9

idk exactly how it is supposed to be done...

i know its 4x^2-4x+1\[-12x^3-8x^2+17x-5\div4x^2-4x+1\]

Answer 10

What's taking so long to type?

@jdorta1

Answer 14

no i have to show the work. its not a multiple choice

Answer 15

Okay, so do you still need some more work shown?
Wait, I now know how to get the answer!

? it worked for me

Answer 30

@JakeV8

Answer 31

-20x^2+20x-5
-20x^2+20x-5

ANSWER: -3x-5

Answer 41

ok, so you have the work... do you understand what that means?

Answer 42

well no...

Answer 43

It's basically like regular long division with ordinary numbers.

Answer 44

except it not lol

Answer 45

Look at the first term under the dividing symbol... it's -12x^3, right?

So look at the polynomial outside... starts with 4x^2.

You then divide 4x^2 into -12x^3 to get -3x... that's what goes on top the dividing symbol thingee.

Answer 46

-3x - 5

--------------------
-20x^2+20x-5
-20x^2+20x-5

ANSWER: -3x-5

Answer 47

It should be a -3x, if that's what you're asking.

Answer 48

17x-3x isnt 20x though

Answer 49

and the middle term should be +12x^2, not negative.

Answer 50

oooooooooh wait haha you change the signs

Answer 51

-3x - 5
