The x^2 in the numerator cancels with the x^2 in the denominator. So you are just left with 4x7 which equals 28.
(4x^2)(7/x^2) = 28

It can either be:
(4x)^2*(7/x)2=16x^2*49/x^2
In the latter case, the two x^2 cancel and the only thing left in the numerator is 16*49, which equals ... 784 :):):), if the whole expressions - 4x and 7/x are squared. But since you haven't specified this, Lian's answer seems to be the right one.
