Problem with Diff'ing a rational expression

Keep getting all twisted up in the algebra in finding the first and second derivative of the following

x(third)-4x(squared)/(x-2)(squared)

F’(x)

(x(third)-4x(squared))’(x-2)(squared)-(x(third)-4x(squared))((x-2)(squared))’/(x-2)(fourth)

than

(3x(squared)-8x)(x-2)(squared)-(x(third)-4x(squared)(2)(x-2)(1)/(x-2)(fourth)

than

(x-2)[(3x(squared)-8x)(x-2)-2x(third)+8x(squared)]/(x-2)(fourth)

now stuck

any help on further factoring would be appreciated

Thanks to all, off doing second now

Thanks for all your help, lets see where I end up at

thanks
