Question

Calc question involing H'Hospitals rule. Please help :-)

Answer 1

L'Hopital's *

Answer 2

you have inf/inf
so you can apply that rule

Answer 3

differentiate top and bottom

Answer 4

20x-5/18x

Answer 5

you can do it again since you have inf/inf

Answer 6

OH! Ok ok ok

Answer 7

This is the one you keep doing again until you get an answer

Answer 8

but there is a shorter way
you don't need l'hospital for this one
you have a polynomial on top and bottom
and they both have the same degree
so you can take the limit as:
\[\frac{\text{ coefficient of } x^2 \text{ on top }} {\text{ coefficient of } x^2 \text{ on bottom }}\]
but you will get the same thing doing it the way you chose
