Show that any graph can be properly vertex-colored with (2m)^(1/2) colors, where m is the number of edges.

Many thanks to anyone who can help solve this little bugger
Rearrange for x, so x=?
x/(x-a)=(x-b)/(x-c)

Its been quite a few years since my calculus days so I'm probably missing something obvious. Somebody can probably do this in a couple seconds...
f(x)=y-(1/y)
solve for y.
many thanks

Function with e problem
Prove that e^x >= 1+x for all x in [0,inf).
My solution so far:
I let f(x) = e^x - 1 - x, now if I can prove f is increasing on [0,inf), then it will work, but I have... | 5 | [

Sigma notation
$\sum_{r=1}^{n}\frac {2r}{(2r-1)(2r+1)(2r+3)}$ No need show me the method, just give me the answer, thanks.
From the usual partial fraction decomposition: $\frac {2r}{(2r-1)(2r+1)(2r+3)} = \frac{1}{8} \left( \frac{1}{2r - 1}\right) + \frac{1}{4} \left( \frac{1}{2r + 1}\right) - \frac{3}{8} \left( \frac{... | 5 | [
