1.For the equation 2x^3-3ax^2+a^3-2a=0(where a 不等于0），find the range of values of a for which the equation has 1 real root only.x=0， f(x)=a^3-2a
x=a,    f(x)=-2a
跟住就唔識揾.GG.
2. Find the number of points of intersection between y=x^3-3x^2/2-5x+1 and y=x-a by considering different values of  a.
x=-1, f(x)=9/2+a
x=2 , f(x)=-9+a
我只揾到2個情況，請問如何找其它情況.
