$\begin{matrix}\left(1\right)\left(-4\right)=-4\\ \left(1\right)+\left(-4\right)=-3\end{matrix}$
Learn how to solve limits by direct substitution problems step by step online. Find the limit (x)->(-1)lim((x+1)/(x^2-3x+-4)). Factor the trinomial x^2-3x-4 finding two numbers that multiply to form -4 and added form -3. Thus. Simplifying. Evaluate the limit \lim_{x\to-1}\left(\frac{1}{x-4}\right) by replacing all occurrences of x by -1.
