Homework Statement
[tex]\lim_{x \to {4}}\frac{4 - x^2}{2 - \sqrt{x}}[/tex]
Homework Equations
The Attempt at a Solution
[tex]\lim_{x \to {4}}\frac{4 - x^2}{2 - \sqrt{x}} \cdot \frac{2 + \sqrt{x}}{2 + \sqrt{x}}[/tex]
[tex]= \frac{x(4-x)(2-\sqrt{x})}{(4-x)} = x(2-\sqrt{x}) [/tex]
this equals zero, but is the limit indeterminate at this point?
