SUMMARY
The limit as x approaches 2 for the expression ((sqrt(6-x)-2) / (sqrt(3-x) - 1) can be evaluated without using L'Hôpital's Rule. By multiplying both the numerator and denominator by the conjugate of the denominator, (sqrt(3-x) + 1), the expression simplifies. This method effectively eliminates the indeterminate form and allows for direct evaluation of the limit.
