    Cancelling roots when dividing.

    I'm having issues understanding the cancelling in the question:

    (3-(root)12)/2
    I get:
    (3-2(root)3)/2 This is the answer in the book but can i not simplify it further to 3-(root)3 ?

    no but you can make it like (3-2(root)3)/2 = 3/2 - (root)3

    in latex

    \frac{3-2\sqrt{3}}{2} = \frac{3}{2} - \sqrt{3}
