I have used the quotient rule to differentiate f(x)=20+16x-x^2/4+x^2. This gives the answer f'(x)=16(4-3x-x^2)/(4+x^2)^2. Now I have to find the stationary points of f(x). I understand in principle how to do this but am stuck because f(x) is a fraction, and I am not sure how to manipulate it into a one line sum
