Answer 8

how may I help you tanvi

Answer 9

ah you want me to ask you questions about quadratic inequalities okay get ready

Answer 10

ready :)

Answer 11

Do you have a rough gang of math geeks at your school?

Answer 12

hahaha, i wish :P

Answer 13

okay here comes the first one

Answer 14

\[f(x) = \frac{(2x-1)(x-1)^2(x-2)^2}{(x-2)(x-4)^4}> 0 \]
Find the solution.

Answer 15

maths looks so good with LaTeX

Answer 16

wow...ishaan's gonna to start you off with a sprint

Answer 17

haha! a challenge, accepted. (Geekiness XD)

warm up tanvi ?

Answer 22

sorry, i'm a bit busy, thanks to you :P

Answer 23

I'l be right back, I have some work to do.

Answer 24

So i have f(x) = (4x^4 - 9x^3 + 14x^2 - 9x + 2)/ (x^4 - 16x^3 + 96x^2 - 256x + 256)

is this right?

Answer 25

you said quadratic inequalities right ?
why would you do that

Answer 26

no need to open you just have to solve for x



give me an example what type of questions you mostly do in quadratic inequalities

Answer 27

oh dear god. what HAVE i done?!?!?!?! pls help :) show any working, if possible

Answer 28

I still can't believe you opened that up it's a very tough job.
but first you need to tell me what questions you normally do just a small example.

Answer 31

okay mistake's mine I should have asked you before sorry

Answer 32

I am posting another one try that

Answer 33

lets see: find the range of values of x for which 2x^2 - 7x + 11 < x^2 - 2x +5.

too simple??

Answer 34

no problem, Ishaan94, it was fun :)

Answer 35

\[f(x)={(x-3)(x-5)} > 0 \]Find the Domain.

Answer 36

oh I see you can do this one.

Answer 37

x<3, x>5

Answer 38

usually they would atleast make us factorise it, or complete the square and THEN do that.

Answer 39

3 5
------------|-------------------|---------------------
++++ ------- +++++++++

Domain (-infinity , 3) U (5 , infinity )

Answer 40

okay I will give you equations.

Answer 42

i think, if you could ask just one or two more, that would be great, 'cuz unfortunately i have to study for another test too. Business :S
