Evaluate a limit at infinity with a radical in denominator

The video tutorial covers the concept of limits, focusing on handling expressions involving square roots as X approaches infinity. It explains dividing expressions by X squared and simplifying them. The tutorial evaluates limits and determines values as X approaches both positive and negative infinity, providing a comprehensive understanding of these mathematical concepts.

Explain the process of dividing both numbers by X squared in the context of the limit evaluation.

What is the significance of the square root of X squared as X approaches infinity?

What happens to the expression 2 over any number as it increases indefinitely?

What is the final value obtained from the limit evaluation discussed in the text?

How does the limit of the expression change when evaluating as X approaches negative infinity?
