    Thank you!
    Let's start with the \sqrt{12}:

    \sqrt{12} = \sqrt{4 \cdot 3} = \sqrt{4} \cdot \sqrt{3}

    = \sqrt{2^2} \cdot \sqrt{3} = 2 \sqrt{3}

    Put that into your fraction and simplify.

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


    Is it like this? Am I allowed to simplify it further by dividing 2 by -2 ?

    Hello,

    be careful! You only can cancel factors never summands:

    \frac{-2+2\sqrt{3}}{-2}=\frac{-2(1-\sqrt{3})}{-2}

    and now it is possible to cancel.
