$\frac{x+4}{\left(x+4\right)\left(x-4\right)}$
Learn how to solve limits by direct substitution problems step by step online. Find the limit of (x+4)/(x^2-16) as x approaches -4. Factor the difference of squares x^2-16 as the product of two conjugated binomials. Simplify the fraction \frac{x+4}{\left(x+4\right)\left(x-4\right)} by x+4. Evaluate the limit \lim_{x\to-4}\left(\frac{1}{x-4}\right) by replacing all occurrences of x by -4.
