    lim ((3- sqrt(x))*(3+ sqrt(x)))/(3- sqrt(x)) =>lim (3- sqrt(x)) plugiin' in the value of x we get 3+sqrt(9) =>3+3 =>6 answer @Gloria63 where sqrt is equal to square root

    \(\displaystyle \lim_{x\rightarrow 9}~\frac{9-x}{3-\sqrt{x}}\) using LHS \(\displaystyle \lim_{x\rightarrow 9}~\frac{1}{\frac{1}{2\sqrt{x}}}\) \(\displaystyle \lim_{x\rightarrow 9}~2\sqrt{x}\)

    LHS goes quite handy, but if you prefer rationalizing then y not:)
