Question

Limits:

Answer 1

Whats your question?

Answer 2

Solve algebraically:
\[\LARGE \lim_{x \rightarrow \infty}~(\sqrt{x^2+7x}-\sqrt{x^2+5x})\]

Answer 3

every time you see a square root, it's always a good idea to try the conjugate

Answer 4

2x / (sqrt(x^2+7x) + sqrt(x^2+5x))

Answer 5

WOW!!!!!!!!!!!!!!! I am in 6 grade right now... that looks soooooooooo hard! O.o

Answer 6

they divide both top and bottom by x

Answer 7

i believe the limit is 1 if my mental calculation is correct

Answer 8

Yup~
Just trying to see if anyone would of suggested a different method other than conjugate.. guess that's the only way xD
Thanks

Answer 9

I'm sure there are other ways to find the limit, but conjugate is the most common method when it comes to square root
