(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

limit[1/(x-2)^3]=-inf as x->2

2. Relevant equations

3. The attempt at a solution

2-delta<x<2 1/(x-2)^3 < M

-delta<x-2<0 (x-2)^3>1/M

(-delta)^3<(x-2)^3<0

=>(-delta)^3=1/M=>-delta=croot(1/M)=>delta=-croot(1/M) ....huh? how could delta be negative?
