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
