Question

Show all work. Find the quotient:
y^4 + 2y-3 /y^2+8

Answer 1

Are you missing parentheses? Is that
(y^4+2y-3)/(y^2+8)?

Answer 2

Sure, it is written out like a fraction, so yes it probably needs parentheses.

Answer 3

Its a different One ..but maybe i can get it... :)

Answer 4

I would help work it out but I am awful with division

Answer 5

y^2 -8
-------------------------------------------
y^2 +8 | y ^4 +2y -3
|
| - (y^4 + 8y^2)
-------------------
-8y^2 +2y -3
-( -8y^2 -64)
--------------
2y + 61

So maybe y^2 -8 is the quotient.........And 2y +61 remainder

Answer 6

I don't Know whether its correct or not......just did it.. :)
If its wrong then pls do tell me..

Answer 7

Nickie_S Pls tell me am i correct?

Answer 8

I wouldn't know, I am awful at this stuff, its good enough for me. lol:)

Answer 9

U must have the ans..

Answer 10

Nope, I do not have the answer. But can you walk me through how you did it?

Answer 11

see its just the normal division

Answer 12

tell me the part u don't understand

Answer 13

I do not even know how to start it!

Answer 14

k...lets make it simple show me some normal division..say fr example 27 divided by 2

Answer 15

See if I can do it on a calculator, I can give you the answer.
13.5

I also do math weird too. Lets see if i was doing it by hand I would start off finding half of 27, which is 13.5.

Answer 16

no..not that way ...i'm showing it to u

Answer 17

2| 27 |13
-2
------
07
-06
-----
1
this is the way i've done with ur question

Answer 18

see in this type of division if u multiply 2 * 13 and add 1 u get 27

Answer 19

here 1 is the remainder ..... 13 quotient ........and 27 dividend ...2 divisor

Answer 20

was this much helpful?

Answer 21

Yes, it was, i can divide evens good, its the odds i dont do well, lol.
So ok, how would we start off this problem:
y^2+8 /y^4 +2y-3

Answer 22

y^2 /y^4 =y^2

Answer 23

y^2/2y=?=1/2

Answer 24

yes thats how i worked it out multiplying the eq by y^2 gives y^4...which help me to cancel frst term

Answer 25

but in eq fr example quadratic ax^2 + bx+ c=0
a,b,c are constants now what if b =0 !!! think about it

Answer 26

See if I can do it on a calculator, I can give you the answer.
13.5

I also do math weird too. Lets see if i was doing it by hand I would start off finding half of 27, which is 13.5.

Answer 27

it would cancel the b out, right, and the x because it goes with the b.

Answer 28

well it would be zero...........and most imprtnt thng is u keep dividing the term as long as the first time cancels out the rest simply adds up into the eq

Answer 29

sometimes the remainder would be 0, while at some other time it may be some const .....like some natural number ...........and sometimes if ur unlucky there is a variable...in the remainder (like in this one ....no matter how long i would go remainder would exist in variable form)

Answer 30

See if I can do it on a calculator, I can give you the answer.
13.5

I also do math weird too. Lets see if i was doing it by hand I would start off finding half of 27, which is 13.5.

Answer 31

OH OK, I think I get it. I have more problems that need solving do you want to try a hand at them?

Answer 32

but only a few ones( they r lengthy and boring :( )....we'l both solve it n try cmpr our answers...

Answer 33

See if I can do it on a calculator, I can give you the answer.
13.5

I also do math weird too. Lets see if i was doing it by hand I would start off finding half of 27, which is 13.5.

Answer 34

Ok.

Answer 35

See if I can do it on a calculator, I can give you the answer.
13.5

I also do math weird too. Lets see if i was doing it by hand I would start off finding half of 27, which is 13.5.

Answer 36

I think I might actually know how to do this one, but I didnt see in my book it worked out like this. Give me some time and I will work it out. 9a^2 -16b^2 / 3a -4b

Answer 37

its a easy one

Answer 38

try coverting the eq. into a^2 -b^2 then apply the identity a^2 - b^2=(a-b)(a+b)...now u'l see denominator gets canceled

Answer 39

9a^2/3a =3a
-16b^2 /-4b =4b

3a+4b

Answer 40

yes !!! thats perfect

Answer 41

See if I can do it on a calculator, I can give you the answer.
13.5

I also do math weird too. Lets see if i was doing it by hand I would start off finding half of 27, which is 13.5.

Answer 42

So then do I do this:
(3a+4b)(3a-4b)

then do foil?

Answer 43

??? i didn't get it

Answer 44

ur last reply ididn't get it?

Answer 45

If I do foil I get the same thing. that equals 9a^2-16b^2

Answer 46

yea ..check the question guess the easiest method and get on it

Answer 47

I said so then do I do this:
(3a+4b)(3a-4b)

Then do FOIL?

Answer 48

So what is the answer?

Answer 49

3a +4b

Answer 50

so r u feeling okay if u get these question?

Answer 51

I understand how to do this one because it has a a and a b in it. So I can divide each one then do FOIL. the others I am so lost still.

So do I do the FOIL? Because that answer was 9a^2-16b^2

Answer 52

no why would u do the foil if u can have answer by much better and easy mehtod

Answer 53

answer is 3a+4b not 9a^2 - 16b^2.....even if its in the book ...subjected to the question u gave me
