Answer 1

\[\large lim_{x\rightarrow2}\frac {4-\sqrt{18-x}}{x-2} \]

this the question?

Answer 2

if yes... you'll need to rationalize the NUMERATOR....

Answer 3

okay so its 4-(Sq.rt 18-x)/x-2 and then ill multipl. by -4+(sq.rt 18-x/x-2 to the top and bottom right?

Answer 4

you'll multiply this to the top and bottom:

\[\large 4+\sqrt{18-x} \]

Answer 5

yeah and i'll get


-16-18+x/-4x+18-x+8-2(sq rt 18-x/ right?????

Answer 6

i mean sq rt 18-x) right?

Answer 7
