limit 1-x^2 =? x---->1          2-√x+3 bantuin ya, thanks :)

[tex] \lim_{x \to 1} \frac{1 - x^{2}}{2 - \sqrt{x + 3} } \\ \lim_{x \to 1} \frac{1 - x^{2}}{2 - \sqrt{x + 3} }. \frac{ 2 + \sqrt{x + 3} }{2 + \sqrt{x + 3} } \\ \lim_{x \to 1} \frac{(1 - x^{2})(2 + \sqrt{x + 3}) }{4 - (x + 3)} \\ \lim_{x \to 1} \frac{(1 - x)(1 + x) (2 + \sqrt{x + 3})}{(1 - x)} \\ \frac{(1 + 1)(2 + \sqrt{1 + 3}) \\ }{1} \\ 2(4) = 8 [/tex]
