Right, this example is from a series review we're working on in Diff Eq and it's something my previous calc professor neglected to require us to know.
" Rewrite the given expression as a sum whose generic term involves xn"
What I tried:
But from here I can't see how that would simplify to something distinguishable with xn in it. Have I attempted it totally wrong or am I just not seeing a trick? Thanks.
edit: Should I just focus on the summation and ignore the (1-x2)?
