$\begin{matrix}\left(-3\right)\left(5\right)=-15\\ \left(-3\right)+\left(5\right)=2\end{matrix}$
Learn how to solve limits by direct substitution problems step by step online. Find the limit (x)->(-5)lim((x+5)/(x^2+2x+-15)). Factor the trinomial x^2+2x-15 finding two numbers that multiply to form -15 and added form 2. Thus. Simplifying. Evaluate the limit \lim_{x\to-5}\left(\frac{1}{x-3}\right) by replacing all occurrences of x by -5.
