what do you need help with?

- anonymous

yeah fire away missy

- anonymous

thank you :) ..in binomial expansion..what's the difference between doing it in ascending powers of x and descending powers of x?
:(

x,x^2,x^3,x^4,.... ascending

- anonymous

Ascending means going up in value from lowest to highest, and descending is the opposite.

- amistre64

cute pic :)

- anonymous

the order of the coefficients is reversed

- anonymous

id say hot..dont mind betts

- amistre64

i got my pic off ebay lol

- anonymous

thanks :) lol

- anonymous

My picture is from a large musical production I was in :) lead male role. audience of 700!

- amistre64

my pic was me waking up to the evil cat laying on me :)

- amistre64

you got good answers? yes?

- anonymous

so that's ascending

- anonymous

yes thank you!

- anonymous

yes the example he game is ascending.

- anonymous

*gave

- amistre64

ascending is to get up, to rise, to fill the balloon and float away into the trees and get stuck becasue you forgot to reel in the tag lines lol

- amistre64

descending is what happens right after that when you jump out and land on the ground

- anonymous

and descending would mean the order of coefficients reversed or..the powers go from higest to lowest? :S

- anonymous

always ready to help gorgeousness..it would mean both i think

- amistre64

engorgeousness too ;)

- anonymous

yes that is correct bettts

- amistre64

..... that didnt sound right lol

- anonymous

it means the coeeficient of x^n is reversed

- anonymous

thank you so much!

- anonymous

all of youu :)

- amistre64

it was thinking of a large pepperoni pizza when i made that comment, dont mind the man behind the curtain :)

- anonymous

makes my day..

- anonymous

this site is so cool :)

- amistre64

yeah, it like being able to go somewhere without leaving the house...unless you go to the library for internet access

- anonymous

yeah ur always welcome...

- anonymous

do y'all mind me giving the question? it's okay you don't have to do it for me :( lol

- anonymous

no we dont

- anonymous

find the first 3 terms in the expansionn of (2x-3/x)^5 in descending powers of x

- amistre64

the question eh....... sounds like a trap :)

- amistre64

is that (-3/x)? or (2x-3)/x ??

- amistre64

1,5,10,10,5,1..... whichever way we go

- anonymous

multiply that by the coefficients of 2 and 3

- amistre64

\[(\frac{2x-3}{x})^5? or (2x-\frac{3}{x})^5\]

- amistre64

gotta know wha tthe question is b4 we can answer it appropriately

- amistre64

does that make sense to you? in other words, the way you wrote the problem is confusing and we need you to clear it up

- amistre64

[2-(3/x)]^5 would be
+(243/x^5)+(810/x^4) +(1080/x^3)

- amistre64

make that:
-(243/x^5)+(810/x^4) -(1080/x^3)

- amistre64

i forgot to factor the negative lol

- anonymous

yeah hes right

- amistre64

the other way would be....
(2x -(3/x))^5
(-3/x)^5 +5(2x)(-3/x)^4 +10(-3/x)^3 (2x)^4
(-240/x) +(810/x^3) - (4320x)

- amistre64

maybe?
