Question

Evaluate the limit: LHospitals Rule: Problem 6

Answer 1

\[\lim_{x \rightarrow infy} \sqrt{x^2+7x+17}-x\]

Answer 2

i got 2(x^2+7x+17)^1/2 for the top

Answer 3

Let's think for a second here, do we truly need l'hospital's rule to solve this limit?

Answer 4

I would like to know what indeterminate form you are getting that is a problem here.

Answer 5

wait no, sorry my mistake miscopied the problem though it was plus x at the end not minus x

Answer 6

I cannot believe I am messing up the algebraic rewritting of this limit but hopefully @hartnn can help you here. Sorry I couldn't help. I must still have linear algebra on the brain!
