$\lim_{x\to8}\left(\frac{7x-56}{2\left(x^2-64\right)}\right)$
Learn how to solve limits by direct substitution problems step by step online. Find the limit (x)->(8)lim((7x-56)/(2x^2-128)). Factor the polynomial 2x^2-128 by it's greatest common factor (GCF): 2. Factor the polynomial 7x-56 by it's greatest common factor (GCF): 7. Simplify \frac{7\left(x-8\right)}{2\left(x^2-64\right)}. Evaluate the limit \lim_{x\to8}\left(\frac{7}{2\left(x+8\right)}\right) by replacing all occurrences of x by 8.
