Hey having a bit of trouble with this question, not sure what to do!(adsbygoogle = window.adsbygoogle || []).push({});

QUESTION - express the fraction in the form a + b rootc / d

3 + root24 / 2 + root6

------------------------------------------

(3 + root24 / 2 + root 6) x (2 - root 6 / 2 - root 6)

Simplifying gives

(6 - 3root6 + 2root24 - root144) / -2

(6 - 3root6 + 2 x 2root6 - root144) /-2

is this right so far? the problem i am having is simplifying the root144 to a root6 inequality!
