Missed opportunity.

Answer 3

That's what I was going for lol

Answer 4

Well then, props. I wasn't sure.

Answer 5

lol

Answer 6

So my "base" (if thats what its called) is \[\frac{ 1 }{ 1-x }\]

If I square it and multiply by two I'll get the expression in my question. Not sure if that has anything to do with it but it seems like a start

Answer 7

Kinda forgotten how to do these, and hungry and need to go to In n Out. I'm not sure if this \[\large \frac{ 2 }{ (1-x)^2 }= 2*\frac{ 1 }{ 1-(2x - x^2) } = ??? ?\]idk, maybe.

Answer 8

no worries. You in cali?

Answer 9

Yep. I was thinkin pizza maybe, but it's been a while since I've been to In N Out, and it is delicious.

Answer 19

Yeah I'm gonna enjoy those fries and animal style burger!\[\large \frac{ 1 }{ 1-x}=1 + x + x^2 +...+x^n+...\]Use eg. 4's method, find deriv. of above:\[\large \frac{ d }{ dx }\left( \frac{ 1 }{ 1-x} \right)=0 + 1+ 2x +...+nx^{n-1}+...\]

Answer 20

Oh I gotcha. Dont think I would have thought of that without seeing it.

Answer 21
