$\frac{1-\sqrt{x}}{\left(1+\sqrt{x}\right)\left(1-\sqrt{x}\right)}$
Learn how to solve limits by direct substitution problems step by step online. Find the limit (x)->(-1)lim((1-x^1/2)/(1-x)). Factor the difference of squares 1-x as the product of two conjugated binomials. Simplify the fraction . Evaluate the limit \lim_{x\to-1}\left(\frac{1}{1+\sqrt{x}}\right) by replacing all occurrences of x by -1. Evaluating the square root using complex numbers.
