Homework Help: Calclulus - L'Hopital's Rule

Posted by Sean on Sunday, March 16, 2008 at 11:07pm.

Evaluate the limit as x -> Infinity

[5x-sqrt(25x^2+4x)]

Direct substitution yields the indeterminate form Infinity - Infinity.

Apparently, according to text book, I have to change that mess into something I can use L'Hopital's Rule on. Except the only example the book gives is something with fractions.

NOTE: For this problem, I do not need the solution itself. I only need this ,(5x-sqrt(25x^2+4x)) in a form that suits L'Hopital's Rule.
