I don't know how to solve it either lol but I just wanted to point out that Cecilia you made one minor mistake since k*k equals K^2 instead of 2k so yeah. Mmmmmm 2k reminds me of Thai food 
.
No matter what I try I end up with k=2N/(k-3)
but then that does not really work since k is not only on one side of the equation but if you multiply it back you get k^2-3k=2N so yeah I give up. Math and me are enemies, well algebra and I are enemies lol.

^lol .. wait. on a second thought. since when did k*k is 2K LOL (don't' know what i was thinking) .. NVM.
k*k -- will be K .. it's like saying 1*1 or 1^2 = 1 LOL
so now ..
it could be interpret
N = ((k*k)-3k)/2
N = (k-3k)/2
N = (-2k)/2
N = -1k
LOl .. or
it could be interpret
N = ((k*k)-3k)/2
N = (k - 3k )/2 (k cancelled k)
N = (-3)/2
N = -1.5
can we at least, have a mathematician come in here and help solve this .. LOl

LOL Cecilia no k*k does not equal k. It's k^2. It's like a*a=a^2 (a squared).

Ok so I don't understand how you got k^2-3k=k-3k?
That's the only part I don't follow. Unless you factored out the k to get k(k-3).
Diamend needs to get in here. She's the one that loves math lol.

^lol ..
what i'm trying to do is ..
K^2 is the same thing as K*K which equal K (unless, there's a value in K greater than 1, then the equation is on a different level LOl )
that's how i got k-3k (k cancel k -- like some physic equation LOl) -- which leave us -3 LOL
yes. whoever, can solve it, come and deal with this. it's driving me nuts here too :loool:

LOL it is indeed very mind boggling.

no, k^2 is not k*k, k^2 is k^2.
im pretty good w/ math, but it's been awhile since i've done this type of math, so let me give it a try.
N = k^2 - 3k/2
im going to move the 2 to the other side so we can keep the k's together by multiplying 2 on both sides.
2N = k^2 - 3k
now, im going to square root the (k^2 - 3k) to get rid of the ^2 and do the same on the other side.
sqrt 2N = k - sqrt 3k
now i can move the sqrt 3k by subtraction to the other side to leave k by itself.
sqrt 2N - sqrt 3k = k
the answer i got is: k = sqrt 2N - sqrt 3k
i don't know, thats a tough one. you don't have the answer, we can work backwards.

^muhaha. my sister did something like that too .. but she turn around and said .. i'm not sure, i'm only a highschool kid LOL
for me. . been over 7 years since i touch math. lOl .. so my formula could be wrong LOL
buit i do know that k^2 is k^2 .. but what i'm saying is that in formula, if we have to write it out. k^2 is like k*k LOl
take for example .. 3^3 is (3*3*3)
hope Daimend can put in her side of equation too .. LOl ..
