asked to find the stationary points this was my working and i don't know if it is correct

f dash of x = -3x^2+3(2x)+9

-3x^2+6x+9

at local max and min f(x) should =0

-3x^2+6x+9=0

3x^2-6x+9

x^2-2x+3=0

stationary points would be at (x+3) (x-3)

but am i right... if not a nudge in the right direction would be a great help

(x-3)(x+1)=0

x=3 x=-1
