Question

Evaluate the limit limx→−1(x2−7x+8/x−5)^2

Answer 1

Just to be clear, is your limit \[\lim_{x \to -1} \left(\frac{x^2-7x+8}{x-5}\right)^2\] ?

Answer 2

yes

Answer 3

Since the denominator is not zero when you plug in x=-1, you can just plug -1 directly into your equation to find the limit
