$\begin{matrix}\left(1\right)\left(-2\right)=-2\\ \left(1\right)+\left(-2\right)=-1\end{matrix}$
Learn how to solve limits by direct substitution problems step by step online. Find the limit (x)->(2)lim((x^2-x+-2)/(x-2)). Factor the trinomial x^2-x-2 finding two numbers that multiply to form -2 and added form -1. Thus. Simplifying. Evaluate the limit \lim_{x\to2}\left(x+1\right) by replacing all occurrences of x by 2.
