$\lim_{x\to-20}\left(\frac{\sqrt{x+31}-\sqrt{11}}{x+20}\right)$
Learn how to solve limits by direct substitution problems step by step online. Find the limit of ((x+31)^1/2-11^1/2)/(x+20) as x approaches -20. Simplifying. Evaluate the limit \lim_{x\to-20}\left(\frac{\sqrt{x+31}-\sqrt{11}}{x+20}\right) by replacing all occurrences of x by -20. Subtract the values 20 and -20. Subtract the values 31 and -20.
