Answer: x=2π/3 and x=4π/3
Step-by-step explanation:
The equation we have is 
. All we have to do is get cosine alone to find the 2 values of x.
Now that we have our cosine left, we can use our unit circle to figure out when does cosx=-1/2. Cosine is the x value of the coordinate.
x=2π/3
x=4π/3
The answer is 9x^3-6x^2+3x
