2. Relevant equations

N/A (L'Hospital (maybe)??

3. The attempt at a solution

so this is what i tried,

since i got infinity - infininty, i tried to convert to a fraction then went on from there to get 2

but using wolfram it gave me -2, mind that it used l'hoapital after converting to a fraction, i didn't find it necessary to apply L'H, since i simplified and didn't get an intermidate form.
