limit as x approaches 2-of (x^2-1)/(x-2)

x \to 2 - lim (\frac{x ^{2} - 1}{x - 2})

- \infty

Solution steps

x \to 2 - lim (\frac{x ^{2} - 1}{x - 2})

\frac{x ^{2} - 1}{x - 2} = (x^{2} - 1) \frac{1}{x - 2}

= x \to 2 - lim ((x^{2} - 1) \frac{1}{x - 2})

x \to a lim [f (x) \cdot g (x)] = x \to a lim f (x) \cdot x \to a lim g (x)

With the exception of indeterminate form

= x \to 2 - lim (x^{2} - 1) \cdot x \to 2 - lim (\frac{1}{x - 2})

x \to 2 - lim (x^{2} - 1) = 3

x \to 2 - lim (\frac{1}{x - 2}) = - \infty

= 3 (- \infty)

Apply Infinity Property:

c \cdot (- \infty) = - \infty

= - \infty
