    simplifying equation with radicals

    Hello Im working on some problems and have come into a problem understanding how something is simplified.
    The problem I am working on starts with -(1/2)^2+1=X^2
    which was simplified to 3^.5/2=X
    Can someone please tell me how this was done it would be very helpful thanks in advance.

    x^2=1-\frac{1}{4}

    x^2=\frac{3}{4}

    x_{1,2}=\pm \frac{\sqrt 3}{2}
