Question

9dc/(d^2-c^2 )-(d-c)/(d+c)

Answer 1

what do you want me to do simplify?

Answer 2

Subtract and simpiliy by removing a factor of 1 when possible

Answer 3

idk thats basically what mine is but without the 1

Answer 4

can't simplify or subtract until you get a GCD

Answer 5

your GCD is going to be (d+c)(d-c)

Answer 6

outkast come look at mine

Answer 7

let outkast help me first

Answer 8

the girl that is looking at mine isnt doing anything

Answer 9

hey thts me

Answer 10

oohhh I did not know

Answer 11

I got the bottom

Answer 12

hahd are u still around

Answer 13

its a little hard to tell what the problem is, is this it?
\[\frac{9dc}{d^2-c^2} - \frac{d-c}{d+c}\]

Answer 14

that is it

Answer 15

and whats the name of the game? simplify? honestly there isnt too much that can be done. We can combine the fractions by getting common denominators, but it will still look messy.

Answer 16

subtract. simplify by removing a factor of 1 if possible

Answer 17

well, noting that:
\[d^2-c^2 = (d+c)(d-c)\] we can multiply the second fraction by a clever form of one, namely:
\[\frac{d-c}{d-c}\] if we do that the second fraction becomes:
\[\frac{d-c}{d+c}*\frac{d-c}{d-c} = \frac{d^2-2dc+c^2}{d^2-c^2}\]
Now you are good to subtract the fractions since their denominators are equal.

Answer 18

im here

Answer 19

okay

Answer 20

what joe is here

Answer 21

no need for me

Answer 22

whats up?

Answer 23

hey man

Answer 24

Answer 25

yo hahd :)

Answer 26

nm u?

Answer 27

same here, its been a pretty nice chill day.

Answer 28

I do not know the answer

Answer 29

ill solve it dw

Answer 30

yo joe when u goin to uni

Answer 31

i converted the second fraction to the same denominator, its just a matter of subtraction now.
@hahd i start school next wed, i cant wait lol

Answer 32

-(d^2-11dc+c^2)/((d-c)(d+c))
there thts the answer

Answer 33

yo joe is uni of texas residence nice?

Answer 34

i say thats good, i dont really see anything else you can do with the problem =/

@hahd i wouldnt know =/ i live off campus in an apartment. From what ive seen though it looks nice.

Answer 35

ah smart person all uni plan on $20000 from me if i stay on res, its ridiculous

Answer 36

wow that seems ridiculous o.O

Answer 37

yh but there's a prog called osap that gives u aloan u can pay it off later

Answer 38

9-2 = 11 or am i looking at two different problems

Answer 39

its 9-(-2)

Answer 40

yes

Answer 41

there is so much work bunched in so many different areas i'm like trying to pick out

Answer 42

ahh indeed

Answer 43

joe gives nice explanation

Answer 44

ha

Answer 45

HAHD ANSWER MY QUESTION NAO

Answer 46

guys can u help me level up one more i wanna sleep a hero

Answer 47

cant havent taken calculus yet

Answer 48

ill give you an easy one

Answer 49

i'll post it in five seconds and you just search p series test

Answer 50

on google

Answer 51

calculus isnt that great imo. there are other harder topics that are more interesting. thats just a personal opinion though.

Answer 52

Likeeee?

Answer 53

i personally like proofing

Answer 54

Number Theory, or Linear Algebra and Matrix Theory, or Modern Abstract Algebra.

Answer 55

i find it confusing at times because of hte slight changes with like variables

Answer 56

i enjoy those more than Calculus. again thats just a personal opinion.

Answer 57

Linear algebra.... I was planning on taing that and calc 3 next semeseter

Answer 58

thanks for telling me tha it's hard

Answer 59

YES THEY ARE AWESOME TOPICs, especially when u study computer science

Answer 60

if its a first class in Linear Algebra its not that hard! sry i dont want to make it seems like impossible.

Answer 61

@hahd yeah those topics have a wide range of applications in computer science.

Answer 62

well i can switch it if i do it soon... would you say linear or differentials was harder?

Answer 63

a family member of mine said that linear algebra was actually simple for her, like the matrices and stuff. But she said that her differential teacher sucked so thats why she hated it

Answer 64

that depends on how the professor teaches the course. I think Linear Algebra could be harder if taught a certain way, but most likely it wont be bad.

Answer 65

like, when i took Linear Algebra (first course), it wasnt bad, but then i sat through a different professors Linear Algebra course to get a better understanding, it was WAY WAY harder than my class.

Answer 66

the only tough thing i find in calc 2 (which i'm in right now) is the changing of variables for stuff like H(y) when the past integrations they used another way of saying it achapter before

Answer 67

haha well i will have the same teacher for both my calc 3 and linear algebra

Answer 68

I think he also teaches the differential this semester too

Answer 69

joe help me with the medal situation

Answer 70

pls

Answer 71

i wana be a hero

Answer 72

i dont think your linear algebra class will be that bad then. Calc 3 is one of the more computational math classes than a theoretical math class. Linear Algebra can be taught either way, as a computational or theoretical.
If your calc 3 professor is teaching Linear Alg., it will probably be computational.

Answer 73

where have you posted Hahd? i'll give you medals.

Answer 74

just click on my name some ppl dont even bothering givin medals after i help them
