    reverse foil complex number?

    Hello,

    I was wondering if it is possible to reverse foil:

    -\frac{1}{2}-\frac{\sqrt{3}}{2}i

    to get:

    (\frac{1}{2}-\frac{\sqrt{3}}{2}i)(\frac{1}{2}-\frac{\sqrt{3}}{2}i)

    The best you can do is take out the common factor of -\frac{1}{2}.


    So -\frac{1}{2} - \frac{\sqrt{3}}{2}i = -\frac{1}{2}(1 - \sqrt{3}i).
