It is known that the function f (x) = x 3-3ax 2+3 is about 20 10, China Volume II, Liberal Arts Mathematics 2 1 Question. ...
F'(x) in the problem is an unary quadratic function in the form of f (x) = ax 2+bx+c.
, if x 1
，x2
For the solution of f(x)=0, then f(x)=a(x-x 1)(x-x2) In this problem, a=3.
，x 1=2-√3
，x2=2+√3
