$\lim_{x\to-8}\left(\frac{x^2+10x+16}{x^2-x-72}\right)$
Learn how to solve limits by direct substitution problems step by step online. Find the limit (x)->(-8)lim((x^2+10x+16)/(-72-xx^2)). Sort the polynomial -72-x+x^2 in descending order to handle it more easily. Factor the trinomial x^2-x-72 finding two numbers that multiply to form -72 and added form -1. Thus. Factor the trinomial x^2+10x+16 finding two numbers that multiply to form 16 and added form 10.
