Exercise
$\lim_{x\to-1}\left(\frac{x^2-4x}{x^2-3x-4}\:\:\:\right)$
Step-by-step Solution
Learn how to solve limits by direct substitution problems step by step online. Find the limit of (x^2-4x)/(x^2-3x+-4) as x approaches -1. Evaluate the limit \lim_{x\to-1}\left(\frac{x^2-4x}{x^2-3x-4}\right) by replacing all occurrences of x by -1. Subtract the values 3 and -4. Calculate the power {\left(-1\right)}^2. Subtract the values 1 and -1.
Find the limit of (x^2-4x)/(x^2-3x+-4) as x approaches -1
Final answer to the exercise
The limit does not exist
