Hi Kazi,
Rationalize the numerator
%28sqrt%28x-4%29-2%29%2Fx
Multiply the numerator (top) and the denominator (bottom) by the conjugate of the numerator: sqrt%28x-4%29%2B2
%28sqrt%28x-4%29-2%29%28sqrt%28x-4%29%2B2%29%2F%28x%28sqrt%28x-4%29%2B2%29%29

%28%28x-4%29-4%29%2F%28x%2Asqrt%28x-4%29%2B2x%29
%28x-8%29%2F%28x%2Asqrt%28x-4%29%2B2x%29
Happy Calculating!!!
