## anonymous 4 years ago find the limit: lim of x is 9, radical x minus 3/x-9, i have the answer but i need someone to work it out please

1. anonymous

$\lim_{x\rightarrow 9}\frac{\sqrt{x}-3}{x-9}$??

2. anonymous

multiply by $\frac{\sqrt{x}+3}{\sqrt{x}+3}$ to get $\frac{x-9}{(x-9)(\sqrt{x}-3)}$ then cancel and replace x by 9
