$\lim_{x\to1}\left(\frac{\sqrt{x+3}-2}{x^2-1}\frac{\sqrt{x+3}+2}{\sqrt{x+3}+2}\right)$

Learn how to solve limits by factoring problems step by step online. Evaluate the limit of ((x+3)^0.5-2)/(x^2-1) as x approaches 1. Applying rationalisation. Multiplying fractions. Solve the product of difference of squares \left(\sqrt{x+3}-2\right)\left(\sqrt{x+3}+2\right). Factor the difference of squares \left(x^2-1\right) as the product of two conjugated binomials.
