$\lim_{x\to5}\left(\frac{x-5}{-x^2+x+20}\right)$
Learn how to solve problems step by step online. Find the limit (x)->(5)lim((x-5)/(20+x-x^2)). Sort the polynomial 20+x-x^2 in descending order to handle it more easily. Factor the trinomial by -1 for an easier handling. Factor the trinomial -\left(x^2+x-20\right) finding two numbers that multiply to form -20 and added form -1. Thus.
