Question

lim[x:0,2[(e^(x)-(1+x))/x^(2)]]=

Answer 1

not sure what the notation means, are you taking the limit at x=0 of 2[(e^(x)-(1+x))/x^(2)??

Answer 2

if that is what you mean, then use L'Hopital's rule and differentiate the top and the bottom and then re-evauluate the limit...you should see that it is non-existent
